When the country of Morgal was conquered by Sana, Emperor Ko assigned Kuan to be the governor of the region. After arriving in Morgal, Lord Kuan wrote a letter to his wife, asking that she come with their children to see the country. Thus, for at least part of the ten year period Morgal was under Sanan rule, Kuan and his family resided in Belinsk. At some point Kuan's brother, Unan, ascended the Sanan throne after a civil war, meaning the family was now part of the Sanan Royal Family. After ten years, Volechek, the son of Morgal's former king, lead the beastmen of Morgal in a revolt. Because Unan was fending off an attack from King Wo, Ko's original successor, Unan could not send support to the troops in Morgal. The Sanans living in Morgal were forced to flee for their lives and Kuan was killed in the battle by Volechek. However, his children escaped to Te Rya Village, while his wife, by chance, had been in Tonfon on a visit.
Kuan was known to have two important possessions: The Umbra Map and an Echo Gem. The Umbra Map reveals the locations of the Umbra Gear and was entrusted to Kuan's son, Ryu Kou. Hou Ju received the Echo Gem, which always come in pairs; by holding an Echo Gem, one can determine if the holder of the other gem is still alive. The other Echo Gem was in the possession of Hinechou.
