Captain Sebarial
Status: Deceased. Properly, permanently, cognitive-shadow-trapped-in-a-gemstone deceased. Do not hold your breath for a sequel. Origin: Nalthis (Returned, Awakener), servant of the goddess Endowment — until he decided he’d rather kill her.
Overview
Every campaign needs one villain who is charming enough that the party keeps taking his money anyway, and Sebarial was that villain wearing a captain’s coat and fencing like he was born mid-parry. He kidnapped the party after the fall of Vedenar, poisoned them for leverage, and then — instead of simply keeping them as hostages — spent the next several months being their patron, their employer, and occasionally their nightmare, extracting “friendship favors” the way other people collect on loans. He backflipped off rigging to parry four combatants at once. He hurled men overboard one-handed without breaking conversation. He once choked Kael half-conscious, drained his Stormlight dry, and went right back to being cheerful about it thirty seconds later. This is not hyperbole for the wiki’s benefit. This is just what a Tuesday with Sebarial looked like.
Underneath the charm was a genuinely tragic engine: a Returned demigod from the shardworld Nalthis, stripped by his own goddess, Endowment, of his memories — including of a daughter he no longer remembers having. He wanted revenge on a cosmic scale, and he had the immortality, the resources, and the patience to actually go get it. He recruited Gavlin into his hidden research lab, The Shallow Crypts, funding world-class fabrial research under the cover story of building “Stormlight-harvesting technology.” The real project, uncovered only through Gavlin’s futuresight and a torn letter from an old acquaintance signed “Cephandrius” — someone who clearly knew exactly what Sebarial was and did not think much of his odds — was this: harvest raw Voidlight from the incoming Everstorm, key his own spiritual identity to Odium through an Orb of Connection, absorb the god of hatred’s power, ascend to godhood himself, and go kill Endowment in person. Not metaphor. Actual deicide, twice over, with the party’s own fabrial as the ignition switch.
He was, for what it’s worth, immune to essentially everything the party could throw at him — standard injury, physical attacks, Soulcasting. In the final confrontation he fought with a summoned Shardblade, supernatural speed, and a signature move the table simply started calling “Daddy’s Home,” because there was no other way to describe what it felt like to be on the receiving end of it.
Key Moments
- Kidnapped and poisoned the party in the aftermath of Vedenar’s fall, then spent the following months as patron, captor, and occasional employer, cashing in “friendship favors” at will.
- Delivered a career-highlight villain line while proposing the endgame to Gavlin: “Would you like to help me kill a god, boy?”
- Ran the hidden research lab The Shallow Crypts with Gavlin and Rilano, funding a Stormlight-reservoir fabrial he secretly needed to fuel his real plan.
- True agenda uncovered via Gavlin’s futuresight and a stolen letter: absorb Odium’s investiture through a stolen god-vessel, ascend, and kill Endowment for stripping his memories.
- Interrogated the party over his mother’s missing gold tooth, casually accused Nucko to his face, then declared him “the innocence of an honest man” after buying a nat-20 deception cover story wholesale. Promised to be “following up.” He was right to be suspicious. He never got the chance to follow up.
- Recovered Hansy from Church of the Yips custody and delivered him back to the party at his final research outpost — one of the very few genuinely decent things he ever did, offered up moments before everything went sideways.
The Final Battle
When the truth broke, so did the room. Immune to injury, immune to Soulcasting, immune to every conventional weapon the party carried, Sebarial should have been unkillable in that fight. The party’s only real answer was his belt — specifically, the golden Raysium dagger riding on it, the one weapon on Roshar that could actually hurt him. Nucko landed a critical 26 Thievery check to cut it loose mid-combat, Ravan snatched it out of the air and grazed Sebarial with it, forcing him to burn his one legendary reaction just to avoid worse, and threw it on toward Torin. Sebarial, cornered and furious, took an unconscious Kael hostage and inflicted the wounds that would ultimately kill him. Torin charged. Chungledown Bim dove into the strike meant for someone else. In the chaos, Nucko — the same man who tripped the one tripwire in Session 1 — scooped the fallen dagger off the ground and drove it straight into Sebarial’s chest.
The blade did the rest. It absorbed his cognitive shadow whole, sealing his consciousness permanently inside the pommel’s gemstone, and dropped his body dead to the floor. The campaign’s final boss, the demigod who backflipped through sword fights and planned to murder two gods in a single afternoon, went down to a pickpocket’s knife-hand and a stolen weapon.
Kael did not survive the same fight. The toll was mutual.
The dagger itself didn’t disappear with him — Nucko carried it afterward, and on his own departure from the party, handed it off to Gavlin rather than keep it. Whatever’s left of Sebarial is currently riding around in Gavlin’s possession, permanently, silently, inside a gemstone. This wiki recommends Gavlin not lose that.
