Nidhogrym has never been a happy dragon. A reluctant ally of the frost giants, this white dragon has grown bitter over the years, and turns his vicious nature against any enemies in their tracks, making it difficult for them to move even if they manage to survive the icy assault.

Nidhogrym has learned to choose some of his friends wisely, however, and has thrived recently through his association with an evil sorcerer. This powerful spellcaster often rides the white dragon into battle, casting protective spells and electrifying his foes with a witch bolt that continues to agonize its victims for several harrowing minutes. Their screams of pain are a delight both to Nidhogrym and his sorcerous companion.
