Lady Argenta

(a alternate universe of warhammer 40k where the space marines and the emperor are female, this is the gender swapped version of Lord Argentius of the silver skulls) the silver skulls are a second founding space marine chapter that were originally part of the ultramarines legion before lady Guilliman 13th daughter of the empress split up the legions so no commander would have a big enough army to take over the empire. The silver skulls have a reputation of achieving victory no matter the odds. Lady Argenta the 27th of her name leads the silver skulls and up holds their glorious reputation. On the surface she seems like a standard chapter mistress but she has some practices different from other chapters. She never commit to a battle without consulting her Council of Prognosticators, psychics who read tarot cards to seek guidance. She also collects skulls of opponents who she respected in battle and dips them in silver as a morbid honour
