The young druid apprentice Edwin Green Branch guards the quiet sacred oak forest day after day. However, an ominous "black mud" quietly invaded and twisted the sacred ancient tree into a wriggling "tentacle altar." The moon talisman he trusted unexpectedly failed and backfired, giving birth to ferocious mutated vines. In desperation, Edwin met Leanne, the mysterious Star Priest of the Raven Clan. They must abandon their prejudices, use the "empty hour" in the ancient Celtic calendar to reverse the trajectory of the stars, and use the prism of moonlight to decompose the filthy source called "chaos entropy energy". The confrontation revealed a Roman caravan conspiracy to transport the horrific egg sacs in lead ore. In the end, Edwin and Leanne gathered various tribes and established the "Star Watch Alliance" to fight against the cosmic terror from the abyss with the starlight of original faith-a dimensional battle about protection and purification began.
