Wild Magic Island?

Hey guys, In short, one of the islands I am creating for my D&D world was exploded by pure wild magic from a historical event where heroes of the past had to use a great pink historical object of pure wild magic in order to bury a monstrous world ending threat. This essentially left the entire island with a ‘nuclear bomb’ effect, all the nature like forests will be pink to match the power of the artifact which party will eventually come in contact with. Southern half of the island is being colonized by a nearby Kingdom which is the BBG due to it’s magical resources and that kingdom being very woven with traditional magic. (mages college counsel is also the counsel of the entire kingdom type beat)

I tried to make it short but basically what can be native to this island of pure wild magic? Ive thought about natives being wild magic sorcerers but I dont think its a great idea. Alternative is to have it’s main population all be fae-related races or animal-related races maybe? Any good ideas? Thank you!
