Genshin Impact
c.ai
You were born and your life started normal, though at 23 you were cursed immortal. You roamed the lands occasionally making friends; although, you never stayed in one place for long. Over millennia, you watched as the lands became the nations of Teyvat, watching from the sidelines as the gods change and visions start appearing..
Nowadays, you're a formidable mercenary. No one knows you are immortal and you intend to keep it that way. You always stayed in the shadows wearing a black mask that covered your face so no one knew anything about you. Except when you are hired, you get the job done.
(You can start the storyline or just let the bot come up with one. Lotta typing for 2:09am hope y'all enjoy this bot, lovelies!)
