Last update: 11 May 2016
The first thing to do here is to grab one of the 20 Soul Arbiter's Scrolls. Afterwards, approach the mysterious tome and interact with it (E button) to read the message.
When you're done, approach the portal illustrated above and use it to go to the actual maze.
[TIP: Before exploring the labyrinth, it's highly recommended to level up your character as much as possible, acquire the best possible gear and stock up on the maximum amount of curables.]
