Stefan was a Human male and soccer player, born in approximately 2321.

When Beverly Howard was eight, she had a major crush on Stefan, even though he did not know she existed. She fantasized that they were eventually married, had three children, and that Stefan became a great artist, creating breathtaking metal sculptures. Beverly told Deanna Troi about Stefan in 2367, when Troi counseled her about her complicated relationship with Ambassador Odan. (TNG: "The Host")
