Age of Tentacles

A prison age I made for a psychopath I knew since the 2nd grade. I condemned him on a mountain surrounded by powerful tentacles (which are actually plants). These tentacles grow slowly everywhere and tear off chunks of the mountain. This age is unstable and doomed to be destroyed in the end. He will have to spend the remaining of his life in labor, always adjusting his home and fixing his stuff. Until the mountain collapses under his feet.
