I cant find roost i go the sawmill but i cant get up the stairs and i dont see any wolfs i really dont know what to do, did i mess something up?

roost is up the stairs in the sawmill immediately after you go up the stairs sebille will talk to you asking to be the one who talks to him.

i think i may be confused in what coordinates is the sawmill

What do you do if you also have Ifan? Like only one talks and no matter who goes first, the first one starts a fight, so like what?
