Another defining trait of the Khans is their tenacity and inability to die out. It is explained in Fallout 2 that the protagonist of Fallout 1 wiped out the original Khans in 2161 except for one member, Darion, who swore vengeance and singlehandedly revived the group as the New Khans. However, they were wiped out once again in 2241 by the very grandchild of the Vault Dweller who had destroyed the original Khans.
