So there's no helm? I know they made an Ancient Falmer Crown to go with the light armor set, but did not release it. Does anyone know if there's anything that will complete the 'matching set' perk in place of the crown???

No, nothing. Even the crown doesn't do it because it's considered apparel, not armor.

You dont have to put "(spoilers)". Its a spoiler section.

I know. It just alleviates my anxiety.

That svcks. :/
