Main OC and the House of Nazarick

The queens of House Butterfly were not the first rulers of Mewni. Before their rule was the rule of a dark master, a leader whose monstrous hordes spread fear into the hearts of men, a tyrant hellbent on the domination of all he saw! This was the rule of the Overlords, a bloodline long thought extinct, but in truth was hiding in the shadows, waiting for the chance to take back the throne of Mewni. After all, evil always finds a way. But there's one problem: the Overlord's heir, Ivan, refuses to follow the path of evil and instead finds friendship and comfort in Star Butterfly!

Rated M for Albedo, some sexual actions and implications, and cursing. Other than that, expect T for teen stuff.
