Factol Hashkar's Reign
Factol Hashkar's Reign was the most recent dating convention used in the city of Sigil, based on the number of years since the most recent factol of the Fraternity of Order, Factol Hashkar, came to power. It is uncertain whether the system will be continued after the assassination of Factol Hashkar in the 130th year, as no formal factol had been selected for a time afterwards.
Previous Factols' Reigns
No solid year ranges have been established for these, and there may be further factols as yet unidentified.
