Questions about the Heroes 4 map editor.

that won't work)). I was thinking something like this: the party meets a hero, a dialogue takes place, and the hero joins the party for a certain amount of time, i.e., for a mission. In this case, we need to kill another hero and several other heroes. And when it's done, this hero automatically leaves the party... or, this hero needs to be escorted somewhere (to the Seekers' house) so that he disappears).
by the way, another question: is it possible for a hero to appear from the Seekers' house? He enters the house and finds a companion there who joins the party.
