I understand the White Mage questline deals with the Greenwrath, but I have not personally done it.
There's one example of it during the main storyline, though: there's an Ala Mhigo refugee who has been targetted by the Green(wood?)wrath. The local wildlife hates him and the Gridanians refuse to help him or his fellow refugees. He even tries to leave them behind but gets attacked and you have to save him (from a goblin robber, which I don't think are part of the Elementals repertoire of creatures, so it was probably just a coincidence).
