Ydde was good friends with Ki-Adi-Mundi, often helping Ki track people on the planet. He was caught overhearing the plans of Cerean Elder Dorr-Femi-Bonmi and Ephant Mon to import swoops and other technology to Cerea in exchange for quantities of malium. He tried to escape the citadel, but was executed for his complicity by the Elder's henchmen.
Ydde was survived by his extended family on Orto.
In 19 BBY, the Jedi Nem Bees assumed Ydde's identity during an undercover mission to Orto.
