The daughter of the resistance member Reger, a young woman of Beta III who is swept up in the violence of the Festival while the Enterprise landing party looks on.
Tula lives with her father Reger in the town visited by the Enterprise crew in the first-season Original Series episode The Return of the Archons. She was played by Brioni Farrell.
She greets the newly arrived strangers in the street and, taking them for visitors from another valley, directs them to her father's house for lodging. At that moment the clock strikes the Red Hour. The quiet crowd turns into a rioting mob, and Tula is seized by the young man Bilar.
When the Festival ends she returns home distraught, and Reger, who is immune to Landru's control, can do nothing but comfort her. McCoy sedates her. Her ordeal shocks the landing party, the sociologist Lindstrom most of all, and shows them the price of Landru's enforced calm.
