Trail of Cthulhu: Eternal Lies
In 1938 this creature was encountered by Howard Defoe, Fr. Carl Meinardus, Jerome, and Prof. Marvin Derrikson. It seemed to have an affinity for liquids as it tried to drain the moisture out of its prey. When Prof. Derrikson and Howard seemingly defeated it, it began reforming until Derrikson used a controlled blast to bring down the chamber, seemingly ending its existence.
