Cob, He Who Croaks

Cob is one of the six greater deities within the world, mostly responsible for the Everbog, the vast area of swampland in the center of the continent. He also populated the swamp with all the creatures found within, most notably the toadfolk known as Bullywugs and the gatorkin. He's also credited with giving the desert-dwelling kobolds the art of trapping, and experimenting with the giant flowers around Mechanus to give them more sentient life, transforming them into the poisonous Flauna.

Mostly appearing as a gigantic toad, Cob's avatar roams the entirety of the murk but is seldom seen by anyone.

Worshippers
The cities of Big Croak and Okrel are where most of Cob's worshippers reside, though all toadfolk and gatorkin hold him in some regard. Most travelers consider it lucky to pay their respects to him while traversing the swamp, often by dropping shiny objects into its muddy waters.

The worship of Cob is almost non-existent outside of the Everbog.

The Swamplord
The avatar of Cob is known as The Swamplord, a gigantic toad residing in the swamp. It has no permanent location, instead preferring to roam randomly. It can spend months just basking in the mud before being disturbed by some lucky (or unlucky) traveler, upon which it awakens and depending on its mood, either eats the traveler, gives them directions, demands tribute or sends them even further into the muck to get lost beyond saving.

The croak of The Swamplord can be heard from miles away, a deep ear shattering sound that is known to make huts collapse and bones tremble. Hearing this croak is thought of to be a good and reassuring by the locals; a sign that Cob is watching over them.
