Durendal (artifact)

Properties
An adamant broadsword once carried by Roland, a paladin of Charlemagne. The sword expresses a supernatural property that grants the wielder virtual invincibility from most known forms of trauma, with the exception of powerful sonic blasts (such as those produced by Roland's Horn) and wounds caused by Durendal's master sword, Joyeuse.

Location
Photographic evidence suggests that Durendal was, at one time, embedded in a wall in Rocamadour, France. However, by the time agents of the Soleil et L'acier (France's PDI) gained permission to secure the artifact, it was

already gone, and its current whereabouts are unknown.

Countermeasures
As previously mentioned, sonic weapons and wounds caused by Joyeuse are the only known methods of harming Durendal's wielder. If any other methods exist, they have either been lost to time, or remain to be discovered.
