Sisters of the Order of the Valorous Heart are driven by the belief that they still must atone for the Sisterhood's acts as an unwitting accomplice to the Renegade High Lord of Terra Goge Vandire during the Age of Apostasy's Reign of Blood in the 36th Millennium. Like their patron Saint Lucia, the Order is highly penitent, always striving for atonement for even the slightest perceived sin. A disproportionate number of Sisters in this Order exile themselves to the Sisters Repentia compared to the other Major Orders of the Adepta Sororitas. Because they are constantly reminded of their part in the Reign of Blood, Sisters of the Valorous Heart can be particularly suspicious of those who would call themselves prophets of the Emperor.
