The Crypt Demon or Spider is an NPC in Dead Cells. She appears to be a scout or a simple guardian of the Forgotten Sepulcher, she advises the player to follow the light, as the major mechanic in the Forgotten Sepulcher is the killing darkness while the player is outside of the light. She is only found in the Forgotten Sepulcher.
- "So this is the anomaly she's looking for..."
- "You've come a long way down beneath the surface, Fallen One."
- "Dark is the path you have chosen..."
- "The light of the guardian monoliths will guide you."
- "But for how long?"
- "Behind you, that big LIGHT, just there!"
- "Follow the light."
- The “She” the Spider is referring to may be The Time Keeper, based on the fact that the Beheaded is a known temporal anomaly as well as a certain end-game cutscene.
