It's this Viking symbol for protection (the logo for my intro and my avatar, which I actually kind of made by accident when I used the real Aegishjalmur as a model, and tried to paint it in red so it would show up in the black background. I was going to completely fill in the white background it came with, but then I got lazy and realized that it looked better the way it is). Hence the ghost shouting a mantra in Old Norse at the blast, to make it go away. Something I picked up in my endless hours of no life surfing the internet and reading.
And was that a typo, or is it really spelled that way? And cool, if it is. Wicked cool.
