Walkthrough
A few tips for successfully completing this quest:
 * Before Accepting this quest make sure you clear the entire Labyrinth out first.
 * Make sure you do not have the Escort of Souls quest running concurrently.
 * After accepting this quest six different groups will spawn throughout the Labyrinth. Each group consists of One Keeper of Souls, Three Terrorweb Dryders, and Three Vengeful Aatxe.
 * Don't target the Vengeful Aatxe until the Keeper of Souls in that group are destroyed, since they are invulnerable to any attacks beforehand.
 * Kill the Terrorweb Dryders if they are preventing you from safely reaching the Keeper of Souls.
 * Once the Keeper of Souls is dead, the Vengeful Aatxe should also die without any effort on your part. If they do not, have the tank continue tanking while the rest of the party moves to a safe location. Once everyone is out of danger, have the tank follow so that the Vengeful Aatxe break aggro and watch them fall.
 * The best approach to this quest is to first activate both the Reaper of the Forgotten Vale and the Reaper of the Ice Wastes. Then accept the quest and use the teleport function to attack the Keeper of Souls from behind. Be sure to study the patrol patterns of the monsters if you aren't familiar with them.
