If you are looking for a name for Dungeons and Dragons Online or off, or any roleplaying fantasy game don’t bother trying to invent a name for a barbarian. Genuine Viking names are amazing. Try Thorfinn Skullsplitter , Eric Bloodaxe or Harald Finehair (Eric’s dad) for a start.
Wow. there’s a Viking name converter on http://gorm.com/name/ Bah. it just gives you a description based on what you choose from a few character traits, none of which sound comically bloodthirsty enough to be interesting.
I just found a list of real Viking first names on http://www.angelfire.com/wy/svenskildbiter/Viking/viknams3.html. Some are good enough to have as real names. All would sound better with a Bluetooth or something as the descriptive bit.
