The Root of Akasha is a vast, enigmatic Bio-Dungeon home to countless variations of flora and fauna. However, it's known for being a place of horror where adventurers who enter never return. Monsters are twisted and corrupted by a mysterious disease that turns them into grotesque, heinous beings. Hunger is a constant companion that preys on all living beings, and those who enter find themselves turning into hosts for the parasite that lurks within. Theo, who was betrayed and killed, finds himself reincarnated as a goblin in the Root of Akasha and struggles to survive against impossible odds while trying to find a way out.
