Tank origin

"Purgation in the name of His eternal glory—this is the vow upon our lips and our banners. We live and are moved by the behests of Saint Celestine. The blood of the innocent shall not be spilled, but the blood of the unholy shall flood out. And if the heresy is not stopped by His word, then fire will suffice. The purifying fire. The redeeming fire. And the heresy will evaporate in it and will be buried forever under a thick layer of ash. For ash is the only form of existence of those who were corrupted. Sisters, mercy is our pride and virtue. But let it stay silent in us today. Today, we let fire speak."
