Seagurt Kay'anin, Captain Commander of the Eleven Knights, became King after defeating the demon halfbreed Vannon with the help of the Sunseeker Union, during the Zanar-a-Marax War in Farsk, thus signaling what we refer to as the Kay'anin Era.

He built the Kingdom of Aldora atop the corpse of Vannon to prevent the Zanar-a-Marax from obtaining his bones, the Eleven Knights becoming the Knights of Aldora, sworn to stand guard against any Zanar-a-Marax threat.

In 12 K.E., the Zanar-a-Marax attacked Aldora in an attempt to steal the remains of Vannon. The demons besieged the city, forcing Kay'anin and his knights to flee north to the Sharavod Mountains. It was there Kay'anin discovered the Emperica Mechanica and obtained the Twelve Guns. With these new weapons, they were able to drive the Zanar-a-Marax out of Aldora.

Kay'anin combined armies from the surrounding kingdoms and formed the Ma'arath Alliance, training them in the use of firearms. In 36 K.E., Kay'anin married Namira Sidri of the Sunseeker Union, strengthening bonds between the two kingdoms. Guns were spread throughout the west, modeled from the Original Twelve.

King Seagurt Kay'anin died in 121 K.E. at the age of 152, his only son Farmon Kay'anin succeeding the throne.
