The Thirteen Fingers
The Tesaki Juusan (The Thirteen Fingers) is the national term for the collection of Provinces under the control of the Emperor. It is commonly referred to as Tesaki, or the Juusan (the Thirteen). It is the largest nation in the known world.
The provinces of Tesaki were originally thirteen separate nations. Although they were actively involved with each other, through trade, travel, and commerce, they remained disjointed, under the control of thirteen separate yet powerful families (some of which still exist today. Around the year 400, however, everything would change. Shinobu Hideyoshi, of the House Hideyoshi, came under control of his family in the territory now known as Klawmakiba. When he came to power, he began a series of strategic partnerships to attain massive control over more territories than his own. He married the daughter of the House Akio. He had his son marry the sister of the new heir to House Hideo. He also entered into several business relationships with the Shinmichi, Iori, and Kazaki families. With this consolidation, and with others willing to join his cabal, it became very easy to ascend to a throne. By 413, Hideyoshi controlled 12 of the 13 provinces (only Shadowfell resisted with force), and by 425 he controlled them all.
Time has passed such that Hideyoshi is now seen as the “Great Unifier”, regardless of the methods necessary to attain that unification. The Juusan have seen a great amount of wealth and prosperity flow in. The Noble House of Shadowfell was eradicated because of their resistance, and no known descendants remain. The other three houses fell into disarray over the careless acts of a few Heads of House that spent or lost all of their wealth over the centuries.
