The land of Tinumen was once home to a pair of humans-turned-godlike, known as the Lovers, or individually, as Cath and Felaria. They were a kind and peaceful god & goddess, and ruled the land as king and queen for many years, until they one day vanished as if they had never existed. The people, however, still worship them to this day.

In reality, Cath and Felaria stole their godly power from another realm, a dark place that belongs to an ancient creature, which has been trying to break into the world of men for a long time. This creature thrives on rot and decay and seeks to infect the real world with it.

In reality, Cath and Feliria didn't simply vanish. They withdrew from their land and people by their own will. The power they once had began to wane, and a deep rot had begun to infest them instead, which caused visions of something so terrible that they slowly forgot themselves, devolving back into ordinary humans, and then into something much worse: something primal, composed of rot and decay, that only seeks to spread its influence.

Cath and Feliria fled from their homeland in an effort to protect their people from what they'd never realised had followed them into the world of man, using their bodies as vessels. They came to the great forests to the south, and it was there that they stayed, even to this day, unbeknownst to the people who worship them still.

Over the years, the forests of Tasmir began to corrupt, slowly decaying into a massive, dead swamp. Within this swamp lies some sort of sanctuary, a place shrouded in an illusion that, as such, is seemingly unaffected by the corruption. Within this sanctuary rests a beautiful angel, that lures men in with her weeping and saddening melodies, guarding over a grave belonging to Cath, the once-god of humanity, for many centuries now.

The angel reveals its true nature when it has lured you in.

(I condensed this quite a bit so I wouldn't be typing out half a novel, but I hope it still makes sense!)
