Gameoverse self-insert who is the Hero from a game with a morality system where choosing the 'good guy' makes the game significantly harder but, assumedly, leads to better win conditions and the best 'true ending' of the game.

"I went on every side quest. I helped everyone who asked. I gave away money constantly. I was always polite and empathetic and non-violent whenever I could even when I REALLY didn't want to be.

In her original game, a classic and mildly gritty fantasy called The Thrall of Nordoom, she was a Paladin and wielded the kind of classically overwrought Elven holy blade forged from starlight type of sword a hero would have by the final act. But as her world crumbled around her she picked up the fallen Villain's cursed weapon instead, a massive talking axe named Splitter who encourages her to day drink and fuck shit up whenever possible.
