Interesting theory, the Fountainhead palace is the first cycle of dragon blood immortality, the second being the Senpou temple. Both areas are reached via crossing a bridge, and are both guarded by a boss. Senpou temple is filled with maple leaf trees wheres the maples are only found at the bridge of the fountainhead palace while the rest are sakura trees. Palace birthed the divine dragon, Senpou temple birthed the divine child. Is it possible that both dragon and child are created false gods? All roads lead to west, home of the dragon.
