Tendōkyū (天道宮) is a massive Treasure Tool in the form of a floating landmass with a large palace constructed on it. It was used by its creator Gavida as his personal quarters until his death, and was then used to house "Flame of Heaven" Alastor, Wilhelmina Carmel and Merihim on their search for the next "Flame-Haired Burning-Eyed Hunter".
BackgroundEditIt has a unique feature: to appear in eternal daytime as opposed to the characteristic of Seireiden, which displays perpetual nighttime. Mathilde and Wilhemina inherited it from Gavida after the latter's death. The two have the knowledge of how Tendokyu can create a passage when it comes close to Seireiden thus making a secret link, for the two Treasure Tools were intended to be pairs.
Like its counterpart Seireiden, it has a cloaking ability called Crypta that makes it invisible to detection by any means. However an accidental blast by Merihim shattered the Crypta, revealing Tendōkyū's location to Bal Masque. The subsequent battle caused the palace to sink into the ocean for the second time. However, years later Wilhelmina Carmel was able to raise it back into the sky to use it to secretly invade Seireiden during the Second Great War.
Later, after Xanadu is created, Wilhelmina, along with 1,225 other Flame Haze who wished to leave, traveled with it through the portal into the new world.
