The Dancing Orochi was the vessel of Tetsuken, and adventuring ship captain and later the Mantis Clan Champion. It was given to Tetsuken by his father when Tetsuken became the Topaz Champion. In 665 the ship sailed into the heart of a Shadowlands fleet, which converged on the Mantis ship. Tetsuken destroyed the enemy with the other ships, but at the cost of his life.
