Thoughts from these first few:
My wife's name is Ursula, which is actually pretty bad-ass in this context...
Foe-render is good too - good verb.
The Axe - simple, elegant, but does it stand out without explanation? I need to be able to spam battle chat with "YOUR FLESH WILL FEED ____"
I like Mactabilis, but latin is the language of my foes (if I stay with the Gaulic theme)... though Frisia is allied with Roma...
Good stuff so far, friends. Food for thought.
