Who: A small boy of St. Andral’s Orphanage — and, until Session 8, the vessel of a shadow demon. Asked his name, he answered: “I’m Mostly Felix.”

Where: The orphanage attic — demon-free, unconscious, breathing. We promised to come back for him.

Status: The demon is in the locket. The boy is just a boy.

First seen: Session 8, whittling with the kitchen’s biggest knife as the window light dimmed around him by itself.

The month of Felix

He arrived at the orphanage a month ago: found entirely unharmed and covered in blood beside his stabbed parents, with no explanation. Since then — children bruised in their sleep, shared nightmares, a boy named Cedric pushed from a window to his death, three boys fled in terror, and every upstairs bedpost carved with a faint rune in Infernal: “Mine.” The headmistress padlocked him in the attic.

The rest of Felix was pleased to chat — villains do love describing their plans. It had been working on the muscly specimen downstairs; it was too late to stop it; and it felt safe telling us because — correctly — “you’re not going to hurt this boy.” Then Drew slipped away to have Milivoj tied down, and it sighed — “do I have to do this early?” — and poured out of the child as black smoke and razor teeth.

The fight, in brief

Steel passed through it — silvered, sneak-attacked, nat-20’d — like it was mostly rumor. It slid through floors. It wore Drew. It drank from Osric’s chest and fattened. It tried Sirius and met warded steel and a sentence it did not expect. What worked was light: Fëanor’s radiance tore it to tatters, and Sirius’s burning blade shredded it into smoke that the open locket drank — and the lid snapped shut.

The locket (read this twice)

A rusted oval locket, an X scratched into the lid, held together by its own abjuration. Inside, an inscription in Celestial that none of us reads. What we understand, on good rolls and angelic intuition:

  • It is the demon’s anchor to this plane — and its prison.
  • Destroying it frees the demon, elsewhere. Not a win.
  • It cannot get out unless someone opens the lid. Someone opened it this morning. For science. We will be more careful.

Working plan: somewhere warded and secret, and we tell no one.

Open questions

  • Who was Felix before — and who stabbed his parents?
  • What does the Celestial inscription say?
  • Who made a prison-locket for a demon, and how did it end up around a small boy’s neck?
