Bargains and Reptiles

Post-Battle of Mewni rewrite with Canon Divergence (and not all chapters have lemon in it). Summary: What if...someone who worked and served for Moon made a deal with Toffee to release both Star and Ludo in exchange for her own life? And what if a human with strange shark/lizard-like abilities has a fated encounter with the regenerating Rasticore? All while learning that neither were Mewman/Human while learning the fateful day between Comet, the last gilled lizard of her own kind, and the dragon/lizard hybrid daughter of a tyrant known as Seth? Mostly Toffee x OC & Rasticore x Koopa Cat's OC story.
