It's night time. Suddenly you accidentally killed a prismatic lacewing. Uh-oh, you fucked up now cuz you just summoned the empress of fucking light. Good thing it's post golem and you got good loot, but it's still a hard boss

She appears out of nowhere, like she just fades in with heavenly light, with a sound of a sad cry of "noooo my lacewing"

Empress of Light: You... You killed my precious Lacewing!!
