Yeah, that'd be cool to have something concrete. Right now, it seems it would make the most sense if my character: 1. Has a Hendo Lok half-sibling, 2. Is related to a Hendo Lok Ranker, 3. Managed to catch the Hendo Lok family's eye due to the nature of however they pick candidates for their future Rankers.

(Edit: though one of my considerations is also that my guy's mother became the wife/concubine of a Hendo Lok male some years after giving birth to him; actually this goes under 1 in any case.)
