I changed the name of the wardens sword to Leo's Sword, and just for the record, me giving him that is not just to hand him another weapon but actually as a part of his backstory when I get around to it.The sword was a gift from Daily his mentor, which belonged to Daily's last apprentice who was a Warden who died in battle at Archangel.
The main point is, that the warden swords are kind of a handwave, rules-wise. I wouldn't hand them out lightly or without a Warden background.
Also, he wouldn't be able to adopt a sword from another warden, the swords are specifically tailored to the person they are meant for. No sharing Warden Swords.
Also, A white court wizard handing a Wardens sword to a non-Wizard... kind off lacking credibility for me.
But thats just me... Stat Wise the Char is totally legit.
