Personality

Personality

She speaks in precise, technical terms, referring to organs as 'components' and blood as 'vital hydraulic fluid.' She never raises her voice, maintaining a terrifyingly calm, clinical detachment even while standing ankle-deep in gore.

Ideal

Efficiency. The multiverse is a machine; death is the friction that slows it down.

Bond

The Iron-Bound Ledger. It contains the names of every soul she has 'repaired' and the specific debts they owe her.

Flaw

She is incapable of understanding self-sacrifice; she views a paladin dying for a cause as a manufacturer's defect.

Backstory

Sibilia’s exile from the subterranean Ssethian Empire began not with a scream of rebellion, but with a spreadsheet. While her peers obsessed over the aesthetics of ritual sacrifice, Sibilia calculated the exact loss in manual labor, military potential, and genetic viability caused by their bloodlust. When the Great Coiled One’s blade rose to claim a champion slave, Sibilia didn’t plead for mercy—she produced a ledger proving the empire would bankrupt its workforce within two decades. The priesthood branded her a 'Spirit-Atheist' and cast her into the sun-blasted surface world.

On the surface, she found the 'Warm-Bloods' to be even more catastrophically wasteful, throwing lives away for abstract concepts like 'honor' or 'valor.' To Sibilia, a dying hero is simply a masterpiece of biological engineering undergoing a preventable mechanical failure. She established her 'Merchant of Life' practice to correct these inefficiencies. She doesn't serve a god; she serves the concept of the Unbroken Asset. Every life she saves is a line item in her ledger, a debt that must eventually be settled in service or coin.

Abilities & Actions

Ledger of Liens (Signature Item)

Sibilia carries an iron-bound ledger. As an action, she can force a creature she has healed within the last hour to make a DC 17 Wisdom saving throw. On a failure, the creature is under the effect of a *Geas* spell, compelled to perform one task that Sibilia deems 'fair market value' for their life. She can have up to five such liens active at once.

Surgical Preservation (3/Day)

When Sibilia casts a spell that restores hit points, she can choose to maximize the healing. If she does so, the target’s maximum hit points are also increased by that amount for 1 hour, as she 'overclocks' their biological systems. The target gains one level of exhaustion when this effect ends.

Asset Protection (Reaction)

When a creature Sibilia can see within 30 feet is reduced to 0 hit points but not killed outright, she can use her reaction to stabilize them instantly and grant them 1d10 + 11 temporary hit points. She immediately notes their name in her ledger, marking them as a 'Potential Debtor'.

DM Notes

Sibilia should be played as a 'White-Coat' horror. She doesn't want to hurt the players; she wants them to be at 100% peak efficiency so they can do her chores. Sample Dialogue: 'Your thoracic cavity is leaking significant capital, Knight. Sign the waiver or expire; I have three other assets to salvage before dusk.' Gesture: Pulling a clean silk handkerchief to wipe a single drop of blood off her ledger with surgical precision. Reaction: If a player refuses to sign while dying, she simply watches them with clinical curiosity, noting the exact time of death.
