Lord Aryon's Box
DISCLAIMER: Your Steps and Tasks may be different
[Step #1] Find Halena Edulan in the tomb raider camp in Salisbury Plains.
Sister Elaydith at the Church in Camleot tells you the story of a battle between Lord Aryon or Avalaon Marsh and Morgana's evil armies. During a pitched battle, Lord Aryon was stabbed by a page with a poisoned dagger. The poison was designed not to kill Lord Aryon, but to leave him in a state of undead.
It was actually Bishop Burhoff that betrayed Lord Aryon. He had charmed the page and then he opened the gates to Morgana's armies. With his last breath, Lord Aryon cursed Bishop Burhoff to suffer the same fate as he. One of Lord Aryon's knights bravely fought his way to Bishop Burhoff and sacrificed his own life to slay Bishop Burhoff. The ghost of Bishop Burhoff still haunts the ruins of the castle in Avalon Marsh, known as Dark Bishop Burhoff.
One of the items that has been recovered from these ruins is a box that belonged to Lord Aryon that contains some important papers that were written by Lord Aryon and some even by King Arthur himself. Unfortunately the key to unlock the box was apparently stolen from Lord Aryon's grave by tomb robbers.
The key is now believed to be in the possession of a tomb robber name Halena Edulan, who can be found in the tomb robber camp in the eastern part of Salisbury Plains. Before the key can be used to unlock the box you will also have to journey to the ruins of the old castle in Avalon Marsh and get a scroll to remove the wards from the box. The scroll you get from the undead remains of Lord Aryon, now know to the locals as Dread Lord Aryon, loc: 41k, 49k.
Once you zone into Salisbury Plains from Camelot Hills, there will be a river on your left. Follow the river away from the road, and after the broken bridge, veer to the right (west) until you come up on the tomb raider camp. There are a few camps along the shoreline, but they are a lot easier to avoid than the random wandering Salisbury Giants and Boars, and this way you don't have to circle around the entire plains just to get to where you want to be.
-Dread Lord Aryon-
Go into Avalon Marsh from Salisbury Plains, and continue on the road past Adribard's Retreat like you were going to Caer Wintrin. When the road forks the first time in Avalaon Marsh, veer left. A little ways down the road you'll see the broken church (looks similar to the manes demons area by the Prydwen bridge), and Dread Lord Aryon will be standing inside the ruins. This is the same castle you will have to go back to for the second quest to kill Bishop Burhoff, as well.
Return both the key and scroll to the church. As a reward you are given a polearm weapon called Lifetaker.
The next quest in this series is:
Bishop Burhoff's Curse
Note from Boudecca of Gaheris:
On Gaheris - can be got anywhere from lvl 28-50. You do NOT get a Polearm called Lifetaker - which was the whole point of doing the quest.
At lvl 50 you receive 40s (!!) and around 13m xp. For lvl 28 this reduces to 6m
