They're eating her!
And then they're gonna eat me!
OH MY GOD!!
Oh, wait, that's goblins trolls, not elves. Whew!
Elves when a herd of elephants wanders on the map:
Elves can now be eaten by grazers. They keep grazers full for 5 years.
Elves that aren’t memoralized will become crazed nature spirits that will do all sorts of !!FUN!! Things like:
Randomly growing saplings(eg. In the middle of a hallway)
Wilting plants
Toppling buildings(constructions included)
Breaking Raw Adamantine
Stimulating trees to not produce fruits
Sucking up all your booze
Harassing your dwarves for using non-grown wood products, giving them bad thoughts
Causing mayor unhappy thoughts by clogging up his schedule with “attend meeting” jobs to complain about the lack of non-grown wood products
Self-trade with elves, offering all your stuff to them and buying like a wood erong instead
Chase away dwarven caravans
Annoy sieges until they leave of boredom
Annoy megabeasts until they leave of boredom
Annoy migrants until they leave of exasperation
Annoy your dwarves until they leave due to being insane
Turn your dead fortress into a Forest Retreat and seed new elves
Etc. Etc.
Elves, being the snooty bastards they are need 5 whole slabs memoralized to them to appease them and make them disappear. Alternatively you can get an animal ghost to eat it and it will disappear.
