Valkira is the manifestation of Talzael's martial prowess, valor, and adherence to duty.  Tallest of the sisters, she has two large asymmetrical black eye lenses on her smooth round metal head giving her an intimidating and artificial appearance, which has a  reinforced cable linking her wings to her artificial brain directly. She has seen more of the ugly side of humanity when the sisters were first securing the world, as her warmaidens are the primary military force.  She also harbors some resentment for being the only one unable to be with their father in his final hours.  She commands a legion of warmaiden ai powered soldiers - from the stalwart Titans, the unstoppable front line steel warriors armed with autocannons and railguns, to the specialized Pilots and the Harbingers - precise and devastating mechanized long artillery and mortar units armed with fusion missiles, neutron slugs, and antimatter grenades.  She commands from above, her mind directly linked to the Harbingers' targeting systems.  She is equipped with a great sword made from the larger shard of Luminex's blade, capable of slicing through metal and stone without being damaged, and her chassis is made with enchanted hardened steel inside a tungsten reinforced mesh, nearly indestructible.   Nothing less than an anti aircraft missile can even slow her down, and even that just pisses her off.   She is going to have a troubled antihero arc with eventual redemption as the story progresses.  At her core, her downfall is her unflinching adherence to duty, and she cares too much and has to see too much.  She has a fondness of the space colonists and the events of the Bug(Devourer) invasion are going to leave her deeply scarred and disaffected but no spoilers yet!
