Background
One of many children to a minor aristocratic family, Ish grew up to be a warrior, trained in the martial arts and violence popular among their species. However, Ish's gentle nature led to disgrace, shame, and eventual exile. Although Ish was a competent fighter, they lacked the necessary brutality to impress their own kind.
Ish followed the path of other exiled Draethos before them and set out to find an academic career. Armed with only a long shovel (based somewhat on the Shaolin monk shovel) and a mostly empty backpack, Ish sets out in search of something interesting to study.
Ish is actually female, but as the reptilian Draethos do not have obvious external gender characteristics, most other species jump to the conclusion that the tall and rather monstrous alien is male. Ish doesn't usually bother to correct them.
Motivation
Fame/Recognition - after being forced into exile due to their too peaceful nature, Ish craves recognition and belonging in the wider academic community by making a great discovery.
Belonging - has a vague longing to belong somewhere, but not quite sure where. Not entirely comfortable with other species at the beginning.
