Taldeer from Dawn of War
Size: 70 MM
From Warhammer Wiki:
Taldeer was a Farseer of either Craftworld Ulthwé (according to the Dawn of War PC game), or Craftworld Biel-tan (according to the Dawn of War novels), and was the leader of the Eldar strike force sent to Lorn V in anticipation of an impending Necron attack. She and her strike force saved General Sturnn's men on two different occasions, without them knowing until much later. When General Sturnn returned the favor by shielding the Eldar from a huge Ork WAAAGH!, the two races formed a temporary (and uneasy) alliance to further their own goals.
Farseer Taldeer later on led a strike force to destroy the Necrons that had arisen on Kronus, that the forces of the Tau were trying and failing to keep at bay. Farseer Taldeer's presence on Kronus attracted the attention of the Imperial General Lukas Alexander, who was tasked with chasing down Taldeer after her manipulation of the Imperial Guard on Lorn V.
