Trogdor is an adult red dragon terrorizing the lands between Haversmeet and the Frozen Wastes. He has built a cult, The Brotherhood of Burnination , who worship him as a god. Trogodr promises ascendancy to dragonhood for all true believers; in return his followers scour the continent for powerful magical artifacts and destroy Trogdor's enemies. His goal is to become the most powerful dragon on the continent, which puts him at odds with other dragons in the area.
 
Trogdor delights in destruction and carnage, and refers to his fiery rampages as "burninaton." Peasants, cottages made of flammable materials, and anything that will explode when exposed to fire are his favorite targets.
 
Prior to the siege of Monterra, Trogdor was last seen in Haversmeet, where he destroyed most of the town in retaliation for having the Staff of Shifting Worlds stolen from his horde.
 
Trogdor attempted to recruit Abraxis to his cause, and when the young blue dragon refused, Trogdor and his forces raided Abraxis's lair. Although the Scions were able to defeat Syllin and her kill squad, Abraxis was no match for Trogdor and was burinated from above. Trogdor ate Abraxis's heart, growing even more powerful, and threatened to kill the Scions before they were warped back to Monterra.
 
Trogdor personally oversaw his forces lay siege to Monterra, and managed to burninate the town's defenses as well as a good portion of the army's front line. However, he was intercepted by the father of Abraxis, an ancient blue dragon named Arcadius, who injured Trogdor and forces him to withdraw.
 
With Trogdor removed from the fight and Syllin defeated, Monterra's defenders manage to rout Trogdor's remaining forces. According to Arcadius, Trogdor will never threaten the Southern continent again.  However, Trogdor still remains a threat to mainland Ataaris, and will not take defeat lightly.
