Troll Magic

Yep. Ruks are pretty bright? as long as they are compared to Trolls. But that begs the question, why can Trolls cast magic when they do not appear to follow ant god or demigod? Well, truth be told, Trolls recognise a good thing when they see one and aeons ago, when Mine Trolls worked laboriously for the Zoingots, Wizards taught them many spells to make their work more productive. This included many battle spells allowing Trolls to deal with dangerous denizens of the dark. Now, much of those abilities lie with the Rock Trolls, feral descendants of Mine Trolls.
