I mean there’s the Old Ones that makes dyson spheres and also eat stars but they got beaten by space robot ancient Egyptians

Hmm IIRC there’s also space BDSM elves that captures stars and bring it into a pocket universe for energy. Said space BDSM elves managed to murderfuck borne a god of excess and perfection and tore a hole in realspace to literal hell made out of sentient beings’ emotions.

Then some bloke recently make that hole bigger spanning half of the milky way.
