There are some on my site, look at the inventory of my character, on his stat's pic. The red balls are runes. I found my first one pickpocketing a monster in Draak's dungeon on Hero difficulty. You're not there yet
They are useful to increase you knowledge of your favorite spell. I'm still gathering runes, waiting for me to have found my "ultimate" equipment. Then I'll enchant it with Berserker. Gimme some AC!!!
