T'Ket

T'Ket was an Iconian overseeing the invasion of the Milky Way Galaxy in the early 25th century.

Biography
T'Ket was born at some date prior to 200,000 years ago. In this period, her homeworld, Iconia, suffered an orbital bombardment by an alliance of several races which had rebelled against the Iconian Empire. She was one of the few survivors of the attack, and was among the group that possessed the Dream Gem and used it to escape the planet. (TNG novel: The Devil's Heart)

For over 200,000 years, these survivors, including T'Ket, remained isolated from the rest of the galaxy and slowly managed to rebuild their forces and technology. It is known that at some moment the Iconians left the Milky Way galaxy to somewhere in the Andromeda Galaxy. (TNG novel: The Devil's Heart)

The Iconian War
After the beginning of the Iconian War in the early 25th century, T'Ket was among the Iconians overseeing the Iconian Empire’s campaign to conquer the galaxy.

During the Iconian invasion on New Romulus, T'Ket appears in the Hwael Ruins at New Romulus and murders a group of Romulan Republic officers wich had succesfully defended the area from Herald invading forces. (STO mission: Blood of Ancients)

While T'Ket was operating on an Iconian base in the Dinasia system, a group of Alliance officers and a covert team of Klingons led by Emperor Kahless, dubbed the House Pegh, infiltrate the station on an attempt to sabotage the Iconians Omega particle generators. Stating that his people needed a symbol to inspire them in that difficult period in the war, Kahless challenges T'Ket to honorable combat. As they fought, Kahless' team managed to wound T'Ket by modifying a generator outflow, sending a discharge of Omega energy on T'Ket. Kahless then dealt a blow that cut off T'Ket's left arm. Just before receiving the final blow ,T'Ket, thanks to her advanced technology, moved backward of Kahless, striking a fatal blow wich disintegrated him. (STO mission: House Pegh)

During an Alliance mission deep inside Vaadwaur territory, M'Tara, T'Ket, L'Miren, and nine other Iconians congregate in the Kyana system after a group of Alliance officers manage to defeat an entire squad of Heralds and escape. She discusses with her fellow Iconians about the Alliance's unexpected resilience, not knowing they were being watched by that same group of Alliance officers that were safe thanks to a Krenim device that allowed them to stay out of normal space-time. This device functioned as a kind of cloaking device, however much more complex. These alliance representatives, having among them Captain Nog of the Chimera, end up negotiating an agreement with the Krenim Imperium to fight the Iconians. (STO mission: Time in a Bottle)
