Umber

Umber was born as a much more powerful deity, a giant sea god who tormented adventurers who dared cross his waves, demanding lavish gifts in return for safe passage. Those who didn't give those gifts... would find themselves draped in his hungry maw. The humans grew tired of his actions though and conspired with the other gods to send him away and give his ruling of the sea to his younger sister, the Deity of Seafoam. Together they tied the beast up and plunged him into the crust of the earth, where his body was used as a new home for life: The Lush Caves.

 His essence was seeped away, his once monstrous form becoming weak and human-like. creatures the mortals above called "axolotl's" were a mockery of his image, taunting him with chirps and their constant noise. He wanted nothing more than to escape the glowing vines that wrapped around his new form. Yet humanity has a tendency to weaken the environment around them.

As adventurers explored more of the caves, he felt its grasp on him become weaker and weaker, and he managed to claw his way out of the dirt and onto the beaches that he once ruled.  He had dreamed of the day the sun would touch his face again, the saltwater brushing against his gills, yet... now that he was free... he found himself... so tried. He had dreamed of taking his place as the ruler of the ocean back, but now he... just wants to rest, for once in his life. The drain of being forced to never sleep yet feel his body wither away took everything from him. He made a little cottage and dock by the beach, where he now spends his days resting.  Who knows, perhaps someone would rouse the personality from the greedy, fearsome god from his slumber and lead him on his warpath again. Or perhaps he will just live life finally knowing peace.
