Belcorra is the campaign's overarching antagonist: a powerful undead sorcerer and devotee of the outer god Nimbaloth (the Empty Death) who originally constructed the Gauntlight lighthouse and the Abomination Vaults beneath Otari. She was defeated in battle by the original Rose Guard heroes long ago [S5], yet her spirit and legacy have never truly been extinguished. Early investigation established her as the 'Lady of the Light' depicted in a Gauntlight portrait bearing an Aklo inscription — 'I serve you still, you shall be avenged' — and as the architect of a devil-binding contract, aberration breeding programs, and a cult venerating Nimbaloth [S9, S15]. Her personal quarters, journal, and a wood-golem likeness were discovered in the mid-campaign delve [S20, S27]. As the party descended deeper, her reach came into sharper focus. Her journal, translated by Venris, revealed she had found a site of contact with Nimbaloth and deliberately built a temple around it, feeding 'the mouth' so the Empty Death could consume through it [S40]. She recruited Jafki the flesh-warper to breed her 'perfect soldier,' contracted the devil Aravian to raise an army, and kept a shadow-assassin as her chief operative [S49, S44]. Her scrying bowl, still active, dealt crushing mental damage to those who dared look into it — her hateful visage staring back [S56]. Her journal entries confirm her ambition extended to the Gauntlight itself: she intended to make it 'a sword to burn down the world' after the flesh-lattice failed to produce what she wanted [S58]. As of S62, the imp on the lowest level confirms Belcorra personally performed the summoning that brought the devils to the vaults, and a faction under Chefkin has remained loyal, preparing for her return.
6 open hooks remain on this record.
Belcorra's story begins before the campaign's present day, in the founding violence of Otari itself. The original Rose Guard heroes confronted and apparently slew her at the Gauntlight — a lighthouse she built above the Abomination Vaults she had carved into the earth [S5]. That victory was celebrated as a founding myth. What the town did not know was that Belcorra's spirit, her bound servants, and her carefully laid contingencies had survived the defeat.
When the current party entered the Gauntlight, they encountered traces of her everywhere before they encountered her directly. A portrait of a blonde elven woman — 'the Lady of the Light' — hung inside, its Aklo inscription reading 'I serve you still, you shall be avenged' [S9]. The ghost Gerald identified a boathouse portrait of his 'lady Belcorra' and credited her as the architect of the teleportation rooms' design [S12]. Her personal third-floor office, lit by magical Everlight crystals, still held love letters from devoted servants [S13]. A wood golem in the library bore her likeness [S20].
Each of these was evidence of a woman who had inspired fierce loyalty — and whose followers had kept her memory (and her infrastructure) intact for generations.
By the mid-campaign sessions, Belcorra shifted from a shadowy background presence to an active danger. She spoke directly through the possessed dwarf Lazda in a mocking female voice, dismissing the party's victories as her own tests and asserting her faithful still operated within the vaults [S24]. Her spirit had erected a magical barrier as a 'protective eggshell,' and those who sensed deeper in the Gauntlight could feel her expanding — growing more active over the past century rather than fading [S28].
Her servants continued to invoke her name in battle. A dying boss warned that the graveyard would become 'hers,' built on Otari's grave [S23]. An Urdefhan warrior shouted 'War Chieftain Gerfell, Belcorra needs the eye' as he died, establishing that entire factions within the vaults were actively working toward goals she had set [S46].
The translation of Belcorra's journal in sessions 039–040 provided the ideological backbone of her project. She had discovered a location where Nimbaloth — the Empty Death, an outer god opposed to Pharasma — could make contact with the material world. Rather than flee or seal it, she built a temple around it and began feeding 'the mouth,' enabling Nimbaloth to consume through it [S40]. She recruited Jafki, a master flesh-warper, to create her 'perfect soldier,' and contracted the devil Aravian with the explicit goal of raising an army [S49].
Her ambitions for the Gauntlight itself were apocalyptic in scale. When the flesh-lattice failed to produce the results she desired, her journal entries describe her resolve to tear it down and rebuild it to 'obey' — then use the completed Gauntlight as 'a sword to burn down the world' [S58]. Otari's own ghost recalled hearing Belcorra's scream echo from a floor below during the Rose Guard's assault, a sound that should have been physically impossible — hinting that even her apparent defeat may have been engineered [S58].
The physical evidence of her cruelty accumulates through the lower vaults. She burned a hag alive and imprisoned a menagerie of monsters; her hateful visage still lurks in a disused scrying bowl, dealing 28 points of mental damage to Venerus when he looked into it [S56]. A recap in S51 places her final defeat — the quick fall when the floor collapsed into the servants' quarters — at approximately page 253 of the Thresholds of Truth, but the precision of that accounting has done nothing to undo her reach.
The shadow-assassin Cora Fallow Glade operated as her 'chief assassin,' and players note urgency in confronting her before her plans fully materialize [S44]. Her portrait in Vollok's hall of paintings had been cut from the fourth frame — yet the inscription 'I serve you still. You shall be avenged' remained scratched into the empty wood, and Vollok's documented grief at her death (destroying his own workshop) confirms the depth of devotion she commanded [S59, S60].
On the vaults' lowest accessible level, the imp Aravian confirms to the party that Belcorra personally performed the original summoning that brought the devils to this floor via a dedicated summoning chamber. His 'old arrangement' with her is one he is still trying to escape — her contracts outlive her physical form. A faction under Chefkin has remained loyally active within the vaults, chanting 'Belle Cora this, Belle Cora that' and preparing for her return [S62]. The party has not yet reached or confronted whatever remains of Belcorra at the vault's heart, and the question of whether her resurrection or the Gauntlight's weaponization can still be stopped remains the campaign's central unresolved stakes.
