Dancer was purchased by Heralds of Dawn in Curse Of Strahd alongside three of the stable's other riding horses. He was given a new nickname by the adventurers, "Pony Danza", as were his fellow riding horses "Whinny Houston" and "Sarah Jessica Parker." He was immediately renamed by his rider Izek Strazni to be named "Shadowmare", completely against theme.
While used as transport along the Old Svalich Road as normal, he was also employed to be part of a strange type of watercraft: Tobias Villie Broadnose Cogsmith cast a Spell to allow him to walk on water, propelling a boat across Lake Zarovich alongside his fellow horses and Verity. After the adventure, the horses were brought to Argynvostholt, serving the small community until the Slaying Of Strahd.
