Valerian

''"A Crusader never lets a foreign sword touch his shoulders. A Crusader will keep his oaths unless they restrain him from doing good in the world. A Crusader never trusts a Diamond, no matter if they declare themselves Green. A Crusader never falls victim to the blind beauty of a Corona. A Crusader is not a sheep. A Crusador is not his own man, yet his peoples' man". ''

- Valerian repeating his oath to Evangeline.  

Valerian is a Chevalierian knight and one of the Tamerlanean Crusaders. He was bought by Ley's father from a secretive trafficker in a marketplace, who'd smuggled him into Expiree from Azure.
