*This history was discovered by [[Campaign 2 Adventuring Party]] during [[Journey to Laverasala]]. Experiments undertaken by an [[Ancient Sylvan Culture]] in [[Xoctl]] sometime in [[The Age of Elves]]. The experiments involved creating [[Sylvan Experiment Demons|Demons]] that could not be killed and returned to life again and again. The elves even created [[Sylvan Experiment Plane|A Plane]] to hold the fiends, rather than kill them. Ultimately, the fiends seem to have wiped out their creators.
