Reward: 500 Renown, 4200 Gold.
Go to Ancient Cullis Gate in Darkwood. The portal will activate itself once it's fed with enough undead souls. No problem, just slay them until it's on. After a few moments you will find yourself in the frozen land of Hook Coast.
There are a few things to do around the town - check the secrets part of the guide. When you want to continue the quest, reach the place indicated by a golden dot on the map. It seems someone formed a magical barrier in here and you can't pass through here. Teleport yourself back to the Guild and go to Maze's room. Your mother has been kidnapped by Jack again! Take a book from the table and go talk to Guild Master. He will tell you, that if you decide to continue the quest, you will have to abandon all the other tasks (that means all the silver quests in your journal will disappear and you won't be able to complete them). Agree and take the Quest Card once you're ready.
