Surum

The surum is a currency used in some Cominore countries. It is used in Cassai, Umoraie, Al-Etia, Denianskai, Abahoughyate, Kothaar, Tenrili Coauni and Garria. The currency serm, a name derived from surom, is used in Cetaia. In the past, the surum (or surom) was used in parts of Mivha and Erevista as well.

The surum was introduced by Cissocassaian emperor Ban Truriassa Kepithu in the 14th century as a replacement for the lasa, an originally Disjian currency used in central Cominore. Due to the trade network of the thallasocratic Cissocassaian Empire, the surum became a popular trade currency, as it was stable and minted with pure silver. It was adopted by the Cassaian Gulf countries in the 15th century and by the Etian states in 1630. The Kingdom of Coauni, which traded with southern Cassaian merchants a lot, replaced its former currency, the coaunas, with the surum in 1829.
