From Guild Wars Wiki
Now, the Ancient Weapon seems to be guarded by several Enchanted armor.
- The item was originally designed to be used to knock down the Lonely Vigil as part of the Forgotten Wisdom quest. Unfortunately, time did not allow for the quest to be completed, so this was cut just prior to release. It now serves no purpose in the game world and has no effect.
- This item does not always appear.
- The ancient weapon reappears in Guild Wars 2; it can be found in the Durmand Priory's special collections archives.
