The wizard and succubus at the Mere of Dead Men

Sildar found out some information about who turned the goat into a goat as well as their whereabouts:

It was a wizard who used a succubus to lure the dude away after which the goat returned. Assuming the duo had something to do with it, they were seen going into the Mere of Dead Men. Who knows what that wizard and his servant are up to. The Mere is a mysterious place to chose as a home.
