The Great Owlbear Heist of the Xanathar's Guild
The Great Owlbear Heist of the Xanathar's Guild
A hapless Zhentarim fence named Glibbles accidentally sells a priceless stolen owlbear cub to the party, triggering a farcical chain of events involving the Xanathar's criminal network, a bumbling gang of pickpockets, and a surprisingly articulate owlbear with abandonment issues. The party must navigate Waterdeep's criminal underworld while managing an angry crime lord, incompetent minions, and a baby owlbear with the emotional range of a teenager.

The Broken Keel smells of wet rope, stale ale, and something unsettlingly organic you can't quite place. Dockside tavern patrons—a mix of sailors and those who'd rather not be remembered—barely glance as you navigate to a shadowy corner booth, where a nervous halfling man in an oversized coat frantically shoves a small, cloth-draped cage across the table. "Fine, fine, FINE," Glibbles hisses, his eye twitching. "You want the 'merchandise'? It's yours. Twenty gold. Non-refundable. Don't open it until you're three blocks away." Before you can ask questions, the cloth slips, and a small, fuzzy brown creature with enormous eyes and an expression of profound disappointment stares directly at you. It's... adorable? And also, unmistakably, an owlbear cub—something no fence should be selling to random adventurers for pocket change.
Description
This opening scene introduces the party to Glibbles, a minor Zhentarim fence who has spectacularly mismanaged his inventory. The owlbear cub, stolen from a Xanathar's Guild exotic animal operation, has been sitting in his inventory for weeks—a liability he desperately wants gone. The party can attempt to negotiate, intimidate, or simply accept the "deal," but Glibbles has made it clear: once they accept the cub, there's no backing out. The Broken Keel's bartender, a scarred dwarf woman named Shorla, will confirm that Glibbles is "always selling something he shouldn't," but she'll refuse to get involved. Other patrons will deliberately look away if any trouble starts—this is the kind of tavern where discretion is survival.
DM Notes
Allow the party to roll Insight (DC 13) to realize Glibbles is panicking about something, or Perception (DC 12) to notice Xanathar's Guild symbols carved into the tavern's support beams—a warning sign that this location is under Guild observation. If they do, they understand the severity of what they've accidentally bought into. Glibbles will absolutely lie and claim the cub is "just a very ugly dog" if asked directly. His twitching eye gets worse whenever he lies. Let the party's reaction determine pacing: if they're skeptical, Glibbles becomes even more desperate and offers gold to sweeten the deal. If they're bemused, he becomes grateful and disappears before they can ask follow-up questions.

The moment you step out of the Broken Keel with the cub's cage, the streets of Waterdeep seem to shift around you. Within three blocks, you notice them: cloaked figures lingering too long at street corners, a rogue in leather armor pretending to sleep against a wall, a seemingly drunk gnome who's been forty paces behind you for the last two blocks. The owlbear cub, now unclothed by the tavern's dim light, is unmistakable—and absolutely no one in Waterdeep should be transporting one without the Xanathar's explicit permission. A runner, a young tiefling woman with guild tattoos visible on her neck, suddenly appears at your side, walking just a touch too close. "The Boss wants a word," she says casually, as though commenting on the weather. "You've got his property. He'd like it back. Preferably with an explanation."
Description
A street-level encounter with the Xanathar's Guild's enforcement apparatus. The party realizes they've inadvertently caught the attention of Waterdeep's most notorious crime syndicate. The runner, Vex, is professional but not hostile—yet. She'll allow the party a few options: they can attempt to negotiate, run (triggering a chase), or surrender the cub (which defeats the session's central narrative). Vex's tone makes it clear this isn't a negotiation meant to end with violence immediately, but it's also not optional. She'll guide them to a "neutral meeting ground"—a warehouse in the Dock Ward belonging to a merchant who pays protection money to the Xanathar's. The walk there is tense but uneventful; Vex makes small talk to emphasize how cosmopolitan the Xanathar's Guild is ("Boss doesn't even like owlbears that much, honestly").
DM Notes
If the party tries to run, Vex doesn't chase—she simply notes their direction and disappears, only for three thugs (Xanathar Thugs, MM) to intercept them one block later. This is a Medium encounter but designed to show the party they're outnumbered by guild resources, not to kill them. If they try to negotiate on the street, Perception (DC 14) reveals they're being watched from rooftops by at least two crossbowmen. If they surrender the cub immediately, skip to Scene 3 but have the cub suddenly reveal a hidden magical collar engraved with the Xanathar's personal symbol—they'll want it back for sure. The owlbear cub itself should be given a personality: it's anxious, clingy, and occasionally makes small growling sounds that are far too cute to be threatening.
Read Aloud
The warehouse is enormous, empty except for scattered crates and the echo of your footsteps. At the far end, three figures wait: Vex's superior, a scarred half-orc woman named Kullak who exudes the kind of patience that comes with authority; a nervous gnome illusionist called Sparkle who keeps nervously adjusting his hat; and, disturbingly, a perfectly normal-looking man in fine clothes introducing himself as Ambassador Phelps, who claims to represent the Xanathar's "diplomatic interests." Kullak does not smile. "So," she says, her voice a low rumble. "You bought our property. Glibbles is an idiot, but he's a Zhentarim idiot, so we generally prefer he stays alive. You, however, we don't know. The Boss wants the cub. What's your play here?" The owlbear cub, sensing the tension, makes a small whimpering sound and presses against whoever's holding the cage.
Description
The party meets with Xanathar's Guild leadership in a neutral space. This is a negotiation scene designed to give them multiple paths forward. Kullak is the primary negotiator—a warrior who respects strength and clarity. Sparkle is comic relief; he's secretly terrible at his job and keeps suggesting increasingly absurd "solutions" (selling the cub to a wizard, painting it a different color, "just telling the Boss it was a dog"). Ambassador Phelps is the Xanathar's attempt at civility; he'll propose a "business arrangement" where the party becomes temporary guild contractors. The scene should feel threatening but not immediately violent. The warehouse has scattered crates that could be climbed, and multiple exit points—the party can negotiate, fight, or run, but Kullak will give them a genuine chance to explain themselves first.
DM Notes
Allow the party to roll Insight (DC 13) to understand that Kullak genuinely doesn't care about the cub—she cares about maintaining guild authority and the fact that Glibbles screwed up. A party that acknowledges Glibbles' incompetence rather than their own innocence will find Kullak more receptive. Sparkle should be treated as an NPC wildcard: he's not dangerous, but his stupid suggestions ("What if we just gave the cub to the City Guard?" or "I could polymorph it into a chicken!") can derail serious negotiations if the party plays along. If the party proposes returning the cub to Glibbles, Kullak will laugh for the first time and seem genuinely amused. If they propose returning it to someone else, ask who—this might trigger additional plot threads. The Xanathar's are not interested in a fight here unless the party escalates; they just want clarity and either the cub or an explanation for why they can't have it.
Monsters
Tactics
Sparkle, panicking under pressure, attempts to cast a "harmless" spell to calm the owlbear cub but critically fails—the spell backfires and causes the cub to temporarily go into a panic. The cub lashes out defensively (not aggressively—it's scared), triggering the two thugs to try to contain the situation. Sparkle flees immediately, leaving the thugs to deal with the consequences. The thugs are not trying to kill the party; they're trying to subdue the cub and protect themselves. If the party can calm the cub (Animal Handling DC 13, or any spell that soothes/calms), the combat ends immediately and the thugs stand down. If the party attacks the thugs directly, they'll fight back but remain professional.
Terrain
The warehouse is open but cluttered with crates, scaffolding, and hanging chains from loading equipment. There's a 30-foot-tall ceiling, multiple exits, and several areas of darkness (for Stealth checks). The cub's panic causes minor environmental damage—knocked-over crates, broken chains falling—but nothing catastrophic. The ground is clear enough for movement but slick with spilled warehouse residue in some spots (difficult terrain in 10-foot squares).
Read Aloud
Once the chaos settles—Sparkle is long gone, the cub is calmed, and the warehouse is restored to some semblance of order—Kullak surveys the damage with an expression of profound patience. "Well, kid," she says, looking directly at whoever seems to be the party's leader, "you've managed to not completely screw this up. The Boss respects that." She leans against a crate. "Here's the offer: the cub was an exotic acquisition the Boss lost interest in weeks ago. Training it is more trouble than it's worth. You want to keep it? Fine. But you become responsible for it. And if it causes problems in Waterdeep—kills someone important, gets loose in a populated area, anything like that—the Boss expects you to clean it up. You work for the guild, temporarily, at his discretion. No pay, just the privilege of keeping the little monster." She extends a piece of paper with a single symbol burned into it: the Xanathar's eye. "When you need to contact us, or when we need to contact you, use this. Don't lose it. Don't show it to the wrong people. And don't think for a second this makes you guild members. You're temporary assets. Assets that owe a debt." The cub, now calm, looks up at the party with those enormous sad eyes and makes a small, hopeful chirping sound. Kullak watches this and mutters something that might be affection or might be contempt; it's impossible to tell.
Description
The resolution scene where the party's decision crystallizes. If they've negotiated in good faith and handled the combat encounter reasonably, Kullak offers them the "debt contract"—they get to keep the cub but become temporary assets of the Xanathar's Guild. This is comedic rather than dark; Kullak's tone makes clear she's amused by the party's situation rather than genuinely threatening. The cub's personality should shine through here: it's anxious, clingy, and genuinely interested in whoever has taken care of it best during the session. The party now owns a baby owlbear with emotional baggage and a magical collar that marks it as Xanathar's property. If they've refused to cooperate or fought Kullak directly, she'll simply take the cub and remind them that they're now "debtors to the guild" in a much more sinister way. Either way, the session ends with the party's new, complicated relationship with Waterdeep's criminal underworld established.
DM Notes
This scene should feel like a resolution but also a beginning. The party now has a baby owlbear with abandonment issues and a magical collar linking them to the Xanathar's Guild. Allow them to ask questions about the cub's background (Kullak will reveal it was stolen from a temple of Silvanus as a joke), its feeding habits (it's surprisingly omnivorous), or its abilities (the collar suppresses its growth magically—without it, it would reach full size in months). If the party has bonded with the cub during the session, Kullak will tolerate (and secretly enjoy) their protectiveness. If they've been dismissive, she'll note this and remember it for future sessions. The debt contract should feel both comedic (temporary asset status) and real (the magical marker means the guild can find them anywhere in Waterdeep).
A piece of thick parchment with a symbol of the Xanathar's eye burned into it. Acts as a communication token and proof of temporary guild affiliation. The party can use it to send a message to the guild (takes 1 hour and requires a ritual), and the guild can track them within Waterdeep using this object. Non-magical but magically marked.
A young owlbear with enormous sad eyes and a growth-suppression collar magically linked to the Xanathar's. Named Bristlefur by the party (or by Kullak if the party doesn't name it). It has 20 hit points, AC 11, can make a bite attack (+3, 1d6+1 damage), and is intellectually equivalent to a dog but emotionally equivalent to a teenage human. It bonds quickly with whoever feeds it or shows it affection. Its presence in Waterdeep will cause complications, but it's also an invaluable companion for urban adventuring.
Paid as compensation for the trouble caused by Sparkle's failed spell and Glibbles' incompetence. Kullak considers this a gesture of good faith, though she's careful to note it's not a payment—it's a 'minor adjustment for collateral damage.' The guild clearly has money to burn.
Conclusion
Wrap Up
The party walks out of the warehouse with a baby owlbear, a debt marker, and a head-spinning sense that they've somehow made both allies and enemies simultaneously. Kullak's parting words echo as they leave: "Welcome to Waterdeep, kids. Try not to burn anything down." The sun is setting over the city, casting long shadows across the dock district. Bristlefur makes a small, contented chirping sound and settles against whoever is carrying its cage. The streets of Waterdeep stretch ahead, full of possibility and complications.
Cliffhanger
As the party turns a corner near the Broken Keel, they spot Glibbles being escorted by two Zhentarim enforcers toward a small warehouse. He looks terrified. One of the enforcers catches the party's eye, nods in recognition, and mouths a single word: "Later." The message is clear: the Zhentarim know what Glibbles did, and they're displeased. More importantly, they now know exactly who to find if they want to discuss compensation—or revenge.
Next Session Hooks
- The Xanathar's sends the party on their first 'temporary asset' job: retrieving a stolen shipment from a rival guild, with Kullak emphasizing they have three days to complete it. Failure means renegotiation of debt terms.
- Bristlefur's magical collar begins showing signs of failure. A mysterious contact reaches out claiming to know how to remove it—but the removal would void the party's contract with the guild, forcing them to choose between the cub's freedom and their own safety.
- A group of Silvanus clerics arrives in Waterdeep searching for Bristlefur, intending to reclaim the sacred creature they believe was stolen. The party must decide whether to return the cub, hide it, or negotiate with both the clerics and the guild.
