It looks alot like Ice from Asoiaf or Game of Thrones for you show watchers out there, very nice, I wish there was a sword for Dawn, though theres something close.

What sword is the one close to Dawn?, I think Long Claw would be cool

Well to do an Arthur Dayne-like class, I use the agatha Knight with
-Inquisitor armor with white and silver ancient dragon.
-any clothing under the armor is white to give it a bit of a Aerys Kingsguard look
-use the Sword of Dracul (Dawn aka closest looking sword)
based off of this depiction[awoiaf.westeros.org]
-use just a broadsword for secondary
-use throwing axes as they are the least visible for that type of item/weapon
-Finally for the helmet I either go with no helmet because of the Dayne silver/bleach blond hair or the final guard helm if you want to cover the face.

Hope it's a bit accurate and helped!
Kind Regards

If only I had those Skins!

if only :P
