Revan's mask

During the early skirmishes of the Mandalorian Wars, this mask belonged to a Mandalorian female. In 3973 BBY, the mask remained on the shores of the Outer Rim planet Cathar after the woman's death during the Mandalorians' attack on the world. Ten years later, the mask was pivotal in the Jedi Knight Revan's efforts to find evidence of the Cathar species' genocide; Revan claimed the woman's mask as his own, vowing not to remove it until the Mandalorian Neo-Crusaders were defeated permanently. One year after Revan and his faction of Jedi successfully defended the Galactic Republic and vanquished the Mandalorians, Revan declared himself the new Dark Lord of the Sith and ignited the Jedi Civil War. Darth Revan wore the mask up until his capture by the Jedi Order.
