@Giachia
She sold herself to take attention away from the rest of her family running away, because they would have been enslaved/killed as well. Having money really doesn't mean much when your whole family has been labeled traitors by the Royal family.
Well considering this is a fantasy setting with her father "instigating a rebellion", being sold to slavery may have been conditional considering she was also a knight and might start snooping around. Just a thought.
@Giachia I'm guessing they confiscated the Blade Talisman from her father or something when he was executed because she locked surprised when she saw it.
if only she didnt wear a skirt with her armor on page 21, this would have mader her look very noble, but those combinations just always throw me off. looks too much like hinted fan-service...
