Dueling blades

From A Wheel of Time Wiki

Osan'gar and aran'gar were the common names for a matched pair of blades used in the Age of Legends (particularly during the Collapse) for dueling. Aran'gar was the right-hand blade, and osan'gar the left-hand blade.

The dueling spirit was hindered somewhat by the fact that both contestants usually died; both blades were coated with a slow-acting poison. Because of this fact, the game is thought to have been started or perpetuated by Friends of the Dark.

[edit] Third age

Although the dueling form did not survive the Breaking of the World, the names live on in two Forsaken reincarnated by the Dark One: see Aran'gar and Osan'gar. It is likely these names were chosen because of the right and left handed meanings. The Dark One wishes to hold a greater control of them.
