Mos Eisley Mourners
this was the name given to four DX-series assassin droids owned by Jabba the Hutt. The four droids were purchased and programmed to act in the event of Jabba's death. The droids were programmed to request a specific password each week from Jabba himself. If the password was correct, they would deactivate themselves for another week. If, at the end of each week, the droids did not receive the password, their onboard systems fired up and the droids set out to eliminate their targets. Jabba figured that his death would most likely come from a competitor or underling, and he was determined to keep their greedy hands off his fortunes. Each droid was given specific targets - Lady Valarian, Jun Seros, and Bib Fortuna were all in the target database - and, when activated, set out through the streets of Mos Eisley. As they searched for their targets, the droid would mutter woeful cries and mourn the death of the mighty Jabba, while efficiently hunting down their targets. When Jabba died just prior to the Battle of Endor, it was never learned if the ancient droids actually woke up to make their attacks.
