Approach the Crowmaster again. After you listen to the conversation, Find the north-eastern portal to Lostlight. Approach it and press "E", which will take you to a new location [The Tree of Life]. The game will automatically finish the current quest and you will be rewarded with 2300 experience points, and with 10000 gold pieces. Also a new main quest will unlock [Key to Redemption].
[TIP: Like in the case of the journey for the Kingdom of the Dead from Forge Lands, you do not have to be afraid that travelling to Lostlight is a one way ticket. You will be allowed to travel between these two locations freely.]
