The SSVD is one of the repentance enforcement agencies supervised by the Great Court of Heaven. Its area of jurisdiction is the 8th District. Like the Eiserne Jungfrau, this agency is well-known and is tasked with performing heresy interrogations, and most probably carries out executions and sometimes bestowing redemption. It is rumored that this group's leader, 'Wizard-Hunting Wright', also known as the Twenty Wedges is even more powerful than Dlanor the Archbishop of the Eiserne Jungfrau.
The only known member was the former head of the SSVD, Willard H. Wright and was succeeded by an unnamed female member of the SSVD. Most of the members are shown to be female in Requiem of the Golden Witch, with Willard being the only known male. The total number of members are also uncertain. They also have the same uniform as the Eiserne Jungfrau, but with a different crest symbol.
