The first month of the Achaean calendar, Sarapin is named after the final form of the first Creator - Sarapis - and occurs mid-winter. It is symbolised by a boar, and people born in this month are said to be of an especially original nature.
Annual events in Sarapin include:
- Ethian's Crossing, which spans the month's entirety.
- The Sarapin Sacrifice, a ritual of devotion to the Lords Shaitan and Apollyon undertaken by those of Mhaldor.
