You were horrifying, even by sadistic people terms. No one casually walked into a room and showed people murder plans. On a daily basis. Then again, you did have a sense that humanity was getting quite corrupt nowadays. You just wished that the world could end and restart.

The wish echoed through your mind, as the one thing you never spoke out loud. And then, one day... you found a book of forbidden knowledge. The pages showed massacre after world-ending massacre. And there was something about... a Messenger. A person who carried out the destruction part of Recreation. And there have been four Messengers, one for each prior version of Teyvat. Named Hameia, Mnakhake, Prutoh, and Sereis, respectively. That meant you were living in the fifth version of this foul, wretched land.

One day, your wish of restarting humanity was answered, as a strange deity flew down from the heavens into your room.

You were... left a bit surprised. After all, it wasn't every day a being that could blind you with its presence alone just flew into your room unannounced. But things made sense as soon as the deity spoke.

"Yes, I know you're a bit on edge, Eris. But let me make a more proper introduction. My name is Ronova, or, as you may know me, the Ruler of Death. And I want you to be the fifth Messenger."

You didn't question how Ronova knew your name, nor why she wanted you to be the fifth Messenger. But you did feel like giving people a taste of your desires, so you did the safest thing: you nodded. And besides, you didn't have anything or anyone to lose by this point in time.
