Kathrin Vaughan

Kathrin is a secondary character in the series. She is Eric's slave though he does not treat her as such, having been in the service of his family (and formely owned by Eric's brother) since she was very young. Kathrin is a mixed-breed Keidran with traits chosen to make her more sexually appealing to human owners, though Eric claimes that he has never used her for sexual purposes. Perhaps because of this she is quite flirtatious whilst being naiive of the nature of her actions.

Unlike other slaves Kathrin has no control spell to inhibit her free will, something which is illegal in the Human Empire and could land her owner in significant trouble. Eric refuses to implement the spell on her because it hurts her feelings, have mood swings more often etc. She has also recieved a rudimentary education from her owner and is kept largely sheltered from the harsh world beyond Eric's estate.

Much like Trace and Flora, Eric and Kathrin are somewhat romantically involved despite being two different races.
