Petrius P Pandymon was unusual even for a citizen of Annaria. He was wealthy, and to be sure the wealthy can assume the title of eccentric rather than buck-ass crazy, but Petrius was beyond the pale. He started living in a tree after falling in love with the dryad. Liliah, to whom the tree belonged. And being so very rich meant that he could have the tree outfitted with all of the modern conveniences that Anarians are so very fond of.
In spite of the fact that he loved the Dryad so very dearly, she finally had enough of Petrius’s attentions and forsook her tree to go and live with her cousin, a lake sprite, who assured Liliah that lake dryads were allowed to drown their lovers when they grew tired of them. As for Petrius he loved living in the tree so much that he never again ventured out of it, not even for the Empress. I believe that she even visited him a few times, but being as it hurt her neck to crank it upwards to talk to him, and that it was beneath her dignity to climb up in a tree, she declined any future visits.
