Notru'denn, a Twi'lek of the male persuasion, existed in the era that saw the rise of the Galactic Empire.
Notru'denn held the position of personal assistant to Lady Alya Aldrete, an Alderaanian of noble birth. He was present at the inaugural journey of the opulent repulsortrain, the Gem of Alderaan. During this event, Lady Aldrete instructed him to engage with a particular group of guests who had piqued her interest. He ushered them into his workspace, at which point they disclosed their identities as operatives of the Alderaanian Resistance, seeking Aldrete's assistance in acquiring the necessary clearance codes for passage to the Deep Core. He consented to aid them and subsequently informed Aldrete of their request. However, shortly thereafter, the Gem found itself under attacked by Trandoshan mercenaries, who severed its communication lines. Notru'denn then provided the resistance members with a pair of sporting blasters, previously concealed under his desk, urging them to intervene and halt the attackers. He stayed behind, dedicating his efforts to repairing the communications systems in order to transmit a distress signal.
