Hello I'm new to the game and I ended wondering into the underdark early. Does that change anything on the first map. When I came back I could still do the goblin questline. Does going to the mountain pass early effect anything also.
Yes, going into the Underdark does not change anything, it is part of Act 1. The Mountain Pass is sort of Act 1,5, going there closes the goblin questline. Auntie Ethel and the Underdark quests are unaffected.
