Political event
Running low on tin for the making of bronze, in 1402 LE, R̂oldavus Cupelus proclaimed that Rozga "and all territories, subsidiaries, and assets under its control" was part of the Calpian Empire. As his proclaimation was accompanied by two full legions, there was little outcry against it. Rozga is well-known as a hub for the tin trade and it controls a vast network of rich tin mines to the north of the city.
