It had been a while since Layton and his companions had been back from the plane, not only them but also other participants in the trip had gradually returned and with their return, the whole situation of the plane gradually became clear to those who bothered to inquire and had the connection or strength to do so after all the full picture of the events in that plane involved a detached individual.
Apparently, the increasingly fierce conflict between all forces was fueled by an aborigine, from which force he came from it was not clear as he had clones in all forces in the plane, no one could accurately pinpoint his original or main body and he was an immortal trying to get promoted, trying to become detached and to achieve this he had made use of various manipulation to cause the conflict in the plane to involve all forces, increasing the range and damage caused by the war.
