Shida

Shida, real name Shidamoru (with -moru being a suffix designating the leader of the clan) is a being from Sky Country.

Banishment
Shida was punished with a fate worse than destruction- he was sealed into a plate and banished to the waste-disposal dimension, where he would not longer have any contact with Sky Country. It was intended that he drift about in the currents of magic for eternity, in solitude and emptiness, while his mind slowly destroyed itself. But what the denizens of Sky Country didn't know was that millenia of exposure to the currents of magic had created a whole new form of life mimicking Sky Country- Earth. Already half-mad from isolation without any stimulus by this time, Shida was eventually washed to Earth and came into the hands of humans.
