The Dark Origin Forest is a forest located in the battlefield of the Great Spiritual Academy Tournament that was mooted as a place that holds treasures. At its outer region, the forest prevents all sounds from getting out and tries to impale visitors. Failing to impale them, it uses poison to corrode their flesh and spiritual power. Though in its depths, the Dark Origin Forest boasts a Demonic Spiritual Tree, that upon receiving enough blood, turns into the Divine Wood Palace Remnant.
