Yosev Iost, also known as Comrade Zero, was the founder of the Darukathian People's Revolutionary Army and the first premier of the United Systems Federation. Iost possessed a cold and calculating personality that left little in the way of compassion or mercy. Iost took advantage of the general chaos resulting from the Xaronese invasion to depose the Darukathian Emperor Nyklas II and reorganize the Darukathian Empire into the United Systems Federation.
