A century ago, a group of people existed that planted and raised the mushroom forest, which eric woke up in the other day. These people grew many types of mushrooms, one of which are green and irresistible, which the two couple fed on the other day. Those mushrooms weren’t supposed to be eaten, but to only be used in making antidotes for sick people. If eaten, the person shall turn into a tree, as the same type of tree that grows the same type of mushroom. To turn back the person into his or her former form, another person must be sacrificed. That person must be one of the founders of the mushroom forest, or a descendent of that group … in our case, the general is the only known living candidate.
