Walkthrough
You can take this quest on the side as you adventure through the Underworld. It does not spawn very disasterous spawns like some of the other quests and it will open many quests as each Reaper freed will offer new quests and facilitate travel.

You will need to travel to the location of each Reaper (a monument of Grenth) and defeat the group of three Terrorweb Dryders spawned by the quest. Once they are defeated, the Reaper of that specific area will appear.

As the quest suggests, once a Reaper is freed, you will be able to speak to him and he will teleport you to any other Reaper that you have freed. The Reapers also have quests with great experience rewards, but be aware that taking any quests without consulting the party is unwise.

Note: If you are going to venture far in the Underworld you might want to clear the surroundings of the statues of Grenth in the Forgotten Vale and Twin Serpent Mountains before taking this quest. The monsters in those areas are positioned so that the Terrorwebs need to be killed first if present and the other monsters might attack the Reaper after it spawns. IF any one of the Reapers dies your group will die.
