When called upon by the party, Vix led them through the Twisted Thicket to a site of "Ancient Power" after they gifted him a statuette of a Satyr. They were hopeful he knew the location of an Element Stone but it was in fact the Feywild Portal (Twisted Thicket). Here, he used the statuette to activate the portal and abandoned them while they were mid clash with the Summer's Bane Beastfolk.
After the party tracked him down in the Feywild he had been petrified and lost his arm to a Unknown. They saved him, healed him, then chained him for all his trespasses.
Vix, under order, then led them to Exile's Henge and was accepted by Reot Windwalker as a new member of the community, where he remains to this day.
