[DnD]Aboleths are ancient quasi-immortal Cthulhu-esque horrors who live at the bottoms of oceans and deep underground and enslave humanoids to serve them, they are chaotic evil. One captures a slave with a deck of many things and draws swap alignment, how does an aboleth go about being lawful good?

Aboleths love hoarding powerful magical items, and they love enslaving humanoids. So this scenario does not seem too preposterous, they enslave someone and find a Deck of Many Things and experiment with it and have the good or poor fortune to draw one of those cards that swaps your alignment on the alignment axis permanently. So now the chaotic evil horror unto the gods is lawful good. How exactly do you go about being lawful good in a deep subterranean lake or the bottom of the ocean?

They would likely release their slaves (or keep them, but in better conditions, depending on local law). They would likely seek out a local authority that hss a similar alignment (lawful good needs a structure to adhere too typically) and attempt to assist it, within the confines of local law, custom, and their alignment. They would likely do so from the depths, knowing that they could not simply waltz in the front gate and be accepted.
