Dattan is a powerful mage currently residing in the Mages Guild in Hatmandor. He is the head of the resistance against emperor Gandohar who officially disbanded the Mages Guild, but despite their ‘officially disbandment’ they continue to linger on in one form or another. Dattan knows how to locate and enter the Tower of Fangs but refuses to divulge such information until the player retrieves a dragon fang for him.
He uses the dragon fang to give sentience to Verita Crystals gathered from Gorlag’s Cave in order to raise an army of Verita Crystal warrior creatures with the intent of scaring off the Imperials. They would think the Verita Crystal’s (which have magical properties) were trying to protect themselves and in addition to the Verita Crystal warriors killing and chasing off the miners would have no choice but to abandon their mining operation and leave, weakening Gandohar’s forces and his influence.
