Young Corax

(a alternate universe of warhammer 40k where the space marines and the primarchs are female. This is a female version of corvus corax, called corva corax in this universe) Corva is the 19th daughter of the emperor of mankind and the goth of the 21 sisters. As a baby she was taken from the imperial Palace by the gods of choas. She was found by miners on the moon of Lycaeus which was above the planet of the hive world of Kiavahr. The miners were slaves to nobles of Kiavahr but they raised her as their own and taught her honour. At 18 she got the miners to form a freedom fighter army from weapons she stole from the nobles. That was also when she met the emperor who turned out to be her father. He only gave her a space marine army once she totally freed the miners. Which she did by dropping atomic bombs on Kiavahr. The emperor gave her control of the raven guards legion. They were a mix of the people she saved from Lycaeus and from terra. She never trusted the Terran half as they been trained by her older sister horus who she never trusted (and horus hasn't turned evil at this point)
