From their announcement:
Fueled by vengeance, Blood of Martyrs demonstrates an insatiable desire to unleash its twin blades upon infidels who spill Menite Blood. Only its mistress, Thyra, Flame of Sorrow, matches Blood of Martyrs’ thirst for retribution, and the two are a scything whirlwind of righteous destruction on the battlefield.
The Blood of Martyrs Character Heavy Warjack Upgrade Kit is not a complete model. Players will need a Protectorate of Menoth Heavy Plastic Warjack Kit (PIP 32061) in addition to this kit.
