Hi! My name is Davide and I come from Italy, so just forgive my bad
English :)
Me and some of my friends play a roleplaying game setted in the
Middle Earth of Prof. Tolkien, in the northern part of this. There
the peoples speak nordic language, so we have thought that we could
use Old Norse! Also because there the men are very likely to
vikings...
And so here I am, asking you for a translation for an inscription on
a war hammer of the captain of our little city, called in Rohirrim
(old english) Maethelburg.

Scourge of the phantom-wolves, I don't fear shadow or dark.

Then I will try to put this sentence in furthark runes, so anyone
could tell me a good link where I can find advices to do it?
I promise I will show you the hammer when I will draw it with the
inscription!
Thank you very much for your patience and help.
Bye!
