   Summary

   Simon's mutations have changed him more than he knows. As one of the only two humans on Erid, he faces a difficult moral dilemma.

   . . .

   My take on a Vampire!Simon mutation! Featuring lots of bullshit science I made up, which I've added as a supplemental chapter for anyone who likes that sort of stuff.

   This one has a slightly more horror/gross stuff than usual, so pay attention to chapter trigger warnings if that sort of stuff bothers you <3
