Cothrom is a planet composed of thirty-two different islands. Each island is different yet connected through the Adventurer's Guild. Half of the consciousnesses of the world are reincarnated from different worlds. Here they are given a chance to live again in a world that is less restrictive yet more dangerous than their own. Negative emotions create a tainted power that mutates the normal animals while too much negative energy creates creatures falsely called Green Goblins who destroy indescribably.
On island 21 the negative energy overtaking the positive created an energy struggle that adventurers usually even out, but they have slowly declined. Eight years ago, a Hero was summoned to help regain balance, but he is being contained. An older consciousness is summoned, one that has lived alone most of her life. Can her party make a difference in the decline of the island? Can they fulfil their first goal, to find a way to neutralize the Green Goblins so nobody else has to suffer?
