Tarrana was a young Boraalan female and part of the group saved from Boraal II by Doctor Nikolai Rozhenko. Her father was Kateras. She had yet to be betrothed as of 2370.
Without her knowledge, she was moved to Vacca VI aboard the USS Enterprise-D in 2370 and became part of the new village established there.
Tarrana became enamored with Lieutenant Worf, masquerading as a Boraalan seer while the group was being transported. She had been frightened by the "Sign of La Forge", but Worf allayed those fears. Kateras wanted Worf to become Tarrana's husband, much to Worf's chagrin. (TNG: "Homeward")
Tarrana was played by Susan Christy.
