Blood Elf - Yenra Picture Wiki
Blood Elf from World of Warcraft
The blood elves were introduced in Warcraft III: The Frozen Throne after the undead Scourge destroyed the high elf capital of Silvermoon in Quel'Thalas and the source of their power, the Sunwell along with most of the high elf population. The remaining high elves split into two factions—approximately 10% kept their original heritage, but the rest followed Prince Kael'thas Sunstrider (who would eventually go on to betray his people, and in fact all of Azeroth) and began calling themselves sin'dorei (which in their tongue means "children of the blood" - more commonly referred to as blood elves) in homage to their loss. With the leadership of their prince, the blood elves continued to defend their homeland from the Scourge, allying with the naga in the process. Due to their alliance with the naga, Lord Garithos, commander of the Alliance forces in Lordaeron and Kael'thas' superior officer, charged Kael'thas and his troops with treason and imprisoned them in Dalaran. Kael'thas and his lieutenants were rescued by Lady Vashj and her naga from their imprisonment in the underground jails of Dalaran (which contained anti-magic enchantments, once used for the Kirin Tor's pets), and then used a re-opened portal to flee to Outland.
