Dagon was the name of a Great Old One worshipped by the Sea Devils. (PROSE: All-Consuming Fire) His name was invoked by Commander Krellix. (AUDIO: Tidal Wave)

Behind the scenes

 * Dagān was an ancient Semitic fertility god, who, due to being often depicted as part-fish, was adopted by H. P. Lovecraft as an undersea deity worshipped by his creations the Deep Ones, aquatic humanoids who are somewhat similar to the Sea Devils and with whom All-Consuming Fire, as part of its overall crossover with the Cthulhu Mythos, appears to conflate them. Though Lovecraft himself never identified his Dagon as a Great Old One, other writers in the Mythos, such as Derleth, did.
