Hmm.
If I wanted to start putting my college nicknames into tattoos, I'd have to find a good picture of Andre the Giant from The Princess Bride. Since my nickname in college was Fezzik. That and Ogre.
A tattoo of Raesvelg (Hraesvelg, Hraesvelgr, take your pick) would be difficult, what with the whole shapeshifting aspect inherent in it.
