They were chosen to be the permanent servant to the gods; there was another servant named Elsyn, who was given their position at the same time as Iztris. While Iztris tended to the gods, however, Elsyn was asked to watch over the creatures of the earth; they had some kind of correspondence in their early years, although their conversations were few and far between now. There was a large gap between heaven and the earth.
Working for the gods wasn’t quite difficult, but it was far from interesting. Iztris retained more traits from their mortal life than some others—they retained boredom, and they retained annoyance at said boredom—and thus found the task to grow dull. It didn’t help that petty squabbles and arguments were frequent, and being nothing more than a servant Iztris was forced to sit through many of them.
