I dunno.
on one side, concur: this seems like a typo, and putting her as Khan at 32 seems pretty average on the bell curve.
On the OTHER:
When I thought, "well, who was famous at 22?" my mind IMMEDIATLY went to Taylor Swift's song "22" and, yeah:
The Blood Spirits have been going through some rebuilding decades, and If a Taylor-Swift-like Clan Warrior rose to Galaxy command with an absolute one-in-a-million combination of brains, charisma, talent, business savvy, general "je ne sais quoi" AND could kill Blood Adder 'Mechs like they were going out of style, I could 100% see the Clan saying "eh, what the heck, let's give the kid a shot!"
What've they got to lose at that point? ;) ;D
(edit: it's just that the Clans play by different rules, you know? And I can see this going either way: typo, or her being an absolute wunderkid. Would be intresting to see what TPTB say.
I'm hoping for "ruthless Clan Taylor Swift," myself. ;)
