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!
