Vyraetra, The Wretched Wrym

A farmer pauses in revolted fascination to state at a blackened stalk of corn - putrid ooze seeping out from beneath a writhing mass of maggots.
A young child watches in horror as his sister slowly turns to stone inside the hen house as a lizard-like bird skitters between her feet.
A trader on the way to town notices a growing buzzing sound only moment before a swarm of biting flies descends upon him.

Vyraetra has come to this land.

It might have started with a slain godling. It could have been unspeakable treachery or lies that spread discord among beloved brothers. It may have even been the theft of mortal souls. Vyraetra does not speak of the act that began the curse nor of how long it has been cursed to wander the mortal world. Instead, Vyraetra rails against the egotistical gods and their vainglorious supplicants.

Where Vyraetra goes, a great curse follows- rotting the land even as it rots Vyraetra's heart.

Any details of the vile act that earned Vyraetra divine punishment have long since been lost to history.
