Dagon's worshipers are mostly made up of sailors, coastal dwellers, islanders, fishermen, and sea merchants. Most communities worship him out of fear or awe. The Church of Dagon is disorganized, and different locales vary significatively in the way they practice faith in the god. Dagonite clerics can walk unmolested in almost every port, and they are always welcomed aboard ships in hopes that their presence appeases the furious god.
Dagon has a long and complicated relationship with the goddess Ekhidna. The two are often depicted as a couple, other times as rivals or just friends. There was believed to be a time when the two combined their powers to dominate the world, bringing about an age of darkness. This mythical time has long been forgotten by man.
