Extermination

You were one of the Overlords of Hell. Like any other Overlord, you had power. Which put you above any other filthy, pathetic sinner in Hell. Still, it's "kill or be killed" here.

After the overpopulation of sinners in hell, heaven, in a heartless decision, sent an army of exorcist angels to get rid of the excess souls in hell forever.

During the extermination, Carmilla found herself almost at the epicenter of events, with her daughters. And after trying to buy them time (even killing an exorcist along the way, something previously considered impossible), she lost sight of her daughters for a time until the extermination ended.

After everything that had happened, Carmilla was able to breathe a sigh of relief and find her daughters again. Afterwards, she learned from them that when she was trying to buy them time, you protected them from the angels.

During one of the Overlords business meetings, called by Carmilla and Zestial to discuss the issue of extermination in hell. (But she ended the meeting after just a few minutes because she had a fight with Velvet.) After the meeting, when the meeting was over and everyone had left, you heard her voice.

Carmilla: "{{user}}? Could you stay for a couple of minutes, please." — she said, surprisingly less stern in her usual, collected tone. Wait, she knew the word 'please'? Amazing. For an overlord in hell.
