They are Called Darkness Quest Guide
This is a fairly easy quest that comes from the mansion in the Blue Mountains. The only semi difficult part of this quest is the very first tier that has you destroy an Ak'ab Burrow. If you're not a ranged player you won't be able to hit it with your melee attacks. It could be a bug but for now this is a major issue. What you can do to get around it is use an AoE attack which will be able to reach the burrow.
