yeah thats like in a story of Weiss and Hickman \"Gate of Death\" (i think that\'s its name in English because i read it in dutch, called: \"Poort des Doods\" :] )
In that book there were 2 super-powerful races: Patryns and Sartans. The 2 used rune-magic, the Sartans sang the runes and the Patryns drew the runes in the air. Those Patryns looked like humans but the only difference between humans and Patryns were that the skin of a Patryn was full of tattoos (rune-tattoos to make their magic stronger).
It\'s a good strory actually, a serie of 7 books... I just finished them. I surely recommend them to all fantasy-lovers here...
Hmmm, if u dont like fantasy.. WOT R U DOING HERE?!?
...just read the books...
