""Hope will always survive in those who continue to fight. Like you, BD-1. I believe you will find someone just as brave and persistent as you have been."" ― Eno Cordova to BD-1
The BD unit designated BD-1 was an exploration droid. The masculine-programmed droid accompanied Jedi Master Eno Cordova on the Jedi's journey to explore the history of the Zeffo. Cordova later realized that they were in danger, and programmed BD-1's memory to be blocked, only revealed by someone the droid trusts.
BD-1 then remained on Bogano in the vicinity of the Zeffo Vault until 14 BBY, when the Padawan Cal Kestis, a survivor of Order 66, arrived on the planet at the behest of Cere Junda in order to find a holocron key to rebuilding the Order. Kestis quickly gained the support of BD-1, and they entered the vault. Along the way, the droid's scomp link was broken by the local wildlife. Unable to unlock the deepest reaches, Kestis took the droid back to his starship and crew, the Stinger Mantis.
They then traveled to other worlds on their quest to uncover the secrets of the Vault and that of the Zeffo. BD-1 scanned other Zeffo artifacts, showing recordings of Cordova to Kestis. When they were confronted on Zeffo by the Second Sister, BD-1 activated a force field between the combatants, saving Kestis' life. During their journey, Kestis upgraded BD-1 with several different gadgets to assist them, and also repaired the scomp link.
During their exploration of Zeffo, Kestis was stunned by a Haxion Brood droid bounty hunter, and both he and BD-1 were imprisoned on Ordo Eris. Kestis broke them both out, and they were rescued by the Mantis.
Following a Force vision on Dathomir that left the Jedi's lightsaber damaged, they traveled to Ilum for a new kyber crystal. After battling Imperial forces guarding the cave, Kestis finally acquired a new crystal, only for it to break in his hands. The Padawan almost gave in to despair, but with BD-1's support, rallied and completed his new lightsaber. BD-1 was then able to unlock his memory, showing the recording of Cordova.
Kestis then returned to Bogano and gathered the holocron, but it was stolen by the Second Sister, and the Mantis crew followed her to Nur. BD-1 traveled underwater with Kestis to the fortress. They recovered the holocron, but were confronted by Darth Vader. The droid charged the Sith Lord and delivered a shock, but Vader shrugged it off. They only escaped by breaking the tunnel and escaping in the onrush of water. Once back aboard their ship, Kestis decided to destroy the holocron to prevent the Empire from finding the young Force-sensitives, and then asked the crew of their next destination.
As a BD unit, BD-1 was bipedal, and had white plating with black sensors. Designed to assist with exploration in remote and dangerous locations, BD-1 was enthusiastic about research and data collection, but often disregarded self-preservation.
"The scomp link is busted, but this should get you moving for now" ― Cal Kestis
BD-1 was equipped with various tools, including a healing stim dispenser, a thruster for hovering but not flying, a spotlight and a Holoprojector plus a scomp link. During his travels with Cal Kestis, BD-1 was upgraded with a transformer to control Imperial machines, two processing devices to hack probe droids and KX-series security droids and a motor to carry Kestis up ziplines.
BD-1 aided Jedi Master Eno Cordova in research before the Jedi Purge. They travelled the galaxy together and left behind recorded messages that were to be discovered later on. In Archive Seven - Goodbye, Eno Cordova says his final farewell to the droid as he wipes his memory bank, and trusting a worthy person to replace him.
BD-1's paint scheme may be customized by various paint schemes found in chests throughout the game.
