   Summary

   When Simon died on the blood moon, his problems should have been over. When Simon fell into the ocean on Erid, his problems were just beginning.

   Mutated into an aquatic body he doesn't understand, his memories lost behind an endless sea of blood, Simon is drawn to the only other person he sees outside his new home: Ryland Grace.

   Grace is adjusting to life on Erid when his biodome is invaded by an unknown lifeform. A lifetime of curiosity cannot be contained and Grace begins to strike up a friendship with Simon.

   But there's more to Simon than meets the eye, and as the two grow closer, Simon begins to suspect that something else might be using him for its own purposes, endangering not only Grace and Erid, but the entire universe.

   Story inspired by the artwork of mutant merman Simon by torizzzu on Tumblr.

   Updating twice weekly on Sundays and Thursdays.
