This creature is a manifestation of fears, anxieties, or nightmares that incorporates animal elements. It resembles an enormous eyeless wolf-eel covered in strange arcane patterns; it has two separate gaping mouths filled with teeth. It "swims" along the ground - the ground underneath it magically becomes fluidic to allow its passage, whether it's rocks, dirt, or whatever.
It is a thought-seeking elemental that can literally smell thoughts. It feels transitory or intangible somehow, as if it were just passing through reality.
"Thought? Deceit? Progress? Now you're just making it hungry." - Abral, kithkin alchemist
