The Lefthanded Elves (or Left-Handed Elves), also known as Sinistral Mer, were a race of elves from Yokuda. They were the enemies of the Yokudans (ancient Redguards) and fought with them for a thousand years. During the Mythic Era, the Na-Totambu (Yokudan royalty) fought to a standstill among themselves to decide who would lead the charge against the Lefthanded Elves. Leki intervened and a victor emerged, and war was subsequently declared on the Elves. Diagna, an avatar of the HoonDing, brought orichalc weapons to the Yokudans, which were instrumental in defeating the Elves. The Ra Gada's extermination of elven colonies along the coast of Hammerfell is due to their hatred of the Lefthanded Elves. The Redguards no longer speak of the Lefthanded Elves, as recalling the elves' abominations serves only to darken their days.
The Lefthanded Elves' defeat by the Yokudans and the subsequent sinking of Yokuda imply that the race is extinct, although it has been speculated that there may be a link between them and the southern Maormer.
