Wirt

Wirt is a short villager who guards The Passage in Troms. Talk to him to begin the quest The Passage. He isn't allowed to let anyone in that hasn't completed the quest yet, so be sure to do the quest because it is a very useful route.

Quest
To start the quest, you must be a minimum level of level 57. When you are, talk to Wirt, he will lead you across Troms to talk to Ildan.
