T7-O1

T7-O1, known affectionately as Teeseven or T7, was a T7-series astromech droid active during the Great Galactic War, the Cold War, and the Galactic War between the Galactic Republic and the Sith Empire. Manufactured by Duwani Mechanical Products sometime before 3843 BBY, the astromech droid did not undergo a memory wipe during his entire lifetime, allowing him to develop a strong personality and preserve the memories of the dozen or so partners he worked with throughout the years. Originally a repair and pilot droid, Teeseven began working with the Jedi Order in the years before the Great Galactic War as the partner of Jedi Master Ven Zallow, and he went undercover for the Jedi and the Republic Strategic Information Service on multiple occasions during the conflict. Surviving the Sacking of Coruscant and the fall of the Jedi Temple at the end of the war, Teeseven served as a reconnaissance droid for the Order on their homeworld of Tython for much of the Cold War before teaming up with a young Jedi who was the former apprentice of Jedi Master Orgus Din.

Alongside his friend and the Jedi's apprentice Kira Carsen, Teeseven played a pivotal role in halting the plot of the Sith Lord Darth Angral to assault the Republic using stolen superweapons, and after the Knight received the title of Hero of Tython the droid continued to travel the galaxy with his partners. Teeseven's service with the Hero of Tython eventually culminated in a plan to capture the Sith Emperor himself, and the droid accompanied the Hero of Tython during an assault on the Sith capital of Dromund Kaas. The two managed to gain entry to the Emperor's throne room and defeated the Emperor in a fierce confrontation. Afterwards, Teeseven and the rest of the Hero of Tython's companions were awarded the Cross of Glory for their pivotal role in ending the threat of the Sith Empire.
