Trail of Cthulhu: Eternal Lies
Liar from Beyond
According to the writings of Dr. George Ayers, this was the true entity venerated by the cult headed by Ramon Echavarria. However, most in the cult supposed they were worshiping Gol-Gorath. It is unclear what relationship it has with The Thing With a Thousand Mouths.
It may have at one point been confused with the Liar from Beyond or The Thing With a Thousand Mouths. However, like many creatures and entities associated with the Outside, true definitions can be murky. It was recently determined that this entity was, in reality, Y’Golonac.
