This is an Undertale fanfic, specifically a fanfic for slylock-syl's UnderSource comic. The art belongs to her, and i definitely recommend checking out the comic! Syl is an amazing creator, PLEASE go check her out. Now onto the actual description. In this world, there are two Nations- the Nation of Humans, and the Nation of Alters, otherwise known as Monsters. In this tale, we follow two of these Alters, a Naga named Necros, simply protecting the two in his care, and a Siren named Maestro, who has traveled up the wrong river to hide from hunters.. I hope anyone who chooses to read this enjoys!
