Spectres Comic

Nine spectres enter a mysterious mountain in search of an ancient utopia said to grant immortality. There, they uncover records of an undying divine tree, but the mountain holds a far more perilous trial. The spectres are an unconventional kind of concealer, inheritors of an ancient skill whose methods continually change. They appear to save the world, then vanish when their work is done. Of the nine who enter the mountain, only one remains; the others disappear, and the survivor becomes a humanoid being who is neither human nor spectre.
