The Premiogothiq is a deceased Old One that was slain during the first attempted invasion of the universe by the Outer Gates. The monster is massive, measuring hundreds of miles in length, although it is capable of changing it’s size at will.
The creature led the attack against the Athanteen kingdom of Atlantis, after they had managed to Capture the Roark Skull, preventing the link to the Outer Gate from remaining open to allow the arrival of other Old Ones to complete the conquest of the Universe.
The Premiogothiq was slain during the battle, but it’s massive body fell from the sky, driving the Athanteen city of Atlantis beneath the waves. It was a flood of his blood that twisted those remaining into the monsters they are now.
