I wish I could tell you what to do, but I don't know what we'll find. Be ready for anything.

—Stephen to Rose, Shadow Kiss

Stephen is a Dhampir guardian who appeared in Shadow Kiss. He told Dimitri Belikov about the caves at the base of the mountain. He was one of the fifty guardians that went on a mission to rescue a group of Moroi and Dhampirs that were kidnapped and held hostage by the Strigoi. During the mission, while the hostages were been rescued, he and Rose were ordered by Emil to go in the caves to help Dimitri, Alberta, Janine, and the others to fight the Strigoi. He was killed by a Strigoi while trying to make his escape.
