The beast before you bears similarities to an earthworm, except it is considerably larger. The beast has a gaping maw filled with tiny sharp teeth. The phosphorescent slime coating the worm serves to both protect the beast and perhaps distract its foes.
The phosphorescent worm has a maneuver attack with yet-unknown consequences, affecting all creatures and players in the room:
A searing wave of white light flows out from a phosphorescent worm!
The wave of white envelops you!
You're unaffected by the light.
The wave of white light emanating from the phosphorescent worm envelops a massive grahnk.
The massive grahnk is unaffected by the wave of white light.
The wave of white light emanating from the phosphorescent worm envelops a luminous arachnid.
The luminous arachnid is unaffected by the wave of white light.
This creature is found in the subarea Thurfel's Cellar within Thurfel's Keep.
