The Vermilion Empire stretches from the vastness of the Solari desert to the bustling port city of Gai'an. In the west there are sweeping plains, terraced hills and broad rivers with forested banks. In the east the land rises to a mountain plateau with peaks soaring over 20,000 feet. South of the plateau is a deep desert basin, some 250 miles across which rises again to the rolling grasslands of the Kh'areen steppe. In the north are the two client states of Duang and Yikon that bask in the tropical heat in low lying territory of swamps and jungle.
The Vermilion Empire has a standardized coinage system based around the gotti, li, jet and ku'net.
1 golden gotti = 20 silver li.
1 silver li = 20 copper jet.
1 copper jet = 10 copper ku'net.
The gotti is so named for the face of the emperor on one side of the coin. The name has evolved over various dynasties depending on naming conventions.
Ku'net comes from the Vu word for loaf, or in particular a loaf of bread. This is based on the approximate value it held when first minted.
To put the values in perspective, in 1109 of the Imperial Era at the start of Into This Wild Abyss, a laborer would get between 1 and 1.8 jet a day, a headman 2.2, and a regular soldier 3. Outside the city a shepherd might be on 5 ku'net a day.
In terms of all government bills, payment can be made in coin or produce in kind set against a standardized benchmark. This is the "official rate" per bushel or keg.
Paper money has slowly been making an appearance and is generally styled as a promissory note or letter of credit. Thus large sums can be transferred without heavy bags of coins or the danger of it being easily stolen. Issuance is limited to banks and government ministries. As value of the notes is based on a promise to pay, their practical day-to-day value can fluctuate depending on economic and political conditions.
