11-4D was a protocol droid who was in the service of Darth Plagueis in the years before the rise of the Galactic Empire. Some time before the Clone Wars Darth Plagueis was killed by his Sith apprentice Darth Sidious, who took 11-4D as his inheritance and served Sidious for many years.

11-4D, often referred to as 4D or FourDee, was a multi-appendaged protocol droid that served under several masters in the decades preceding the Clone Wars. 11-4D originally worked in a medical facility on the planet Obroa-Skai before the Togruta Ellin Lah, captain of the freighter Woebegone, became 11-4D's new owner. 67 years before the Battle of Yavin, the Muun Dark Lord of the Sith Darth Plagueis killed the entire crew during the freighter's excursion to Ithor and afterwards took 11-4D into his possession, with the droid easily switching masters to the Muun. From then on, 11-4D helped his master with Plagueis's work, including the Muun's search for immortality.
A year after meeting Darth Plagueis, 11-4D was introduced to the young Sith apprentice who would take the name Darth Sidious. After moving their base of operations from Muunilinst to the moon of Sojourn, 11-4D continued to help Plagueis with his work. A year later, on the eve of the election of Palpatine, Naboo's Senator, to the office of Supreme Chancellor, the Senator killed his Master, leaving 11-4D under Palpatine's possession.
Fall of the Empire
11-4D would continue to serve Darth Sidious into the time of the Galactic Empire as his personal protocol droid, often accompanying him on diplomatic matters. 11-4D was left on Coruscant while Sidious went to oversee the Death Star II's completion and the destruction of the Rebel Alliance. Unfortunately Sidious died during the Battle of Endor and 11-4D was once again left without a master. For the first time in a long time, 11-4D had experienced the feeling of being free, and 11-4D would eventually get bored of it due to him missing his adventures with Darth Plagueis. Eventually 11-4D was found by Snoke who offered to take Plagueis's place in a way Sidious never could. Having no where else to go, 11-4D agreed and became the personal protocol droid of Supreme Leader Snoke of the First Order.
