Before working at the Hunters Lodge, Aidaba worked for an Oseram trader. However, as the Oseram was too inexperienced in trading with the Carja, Aidaba left to become the merchant for the Hunters Lodge.
She is aspiring to open her own shop one day.
Once Aloy has received enough Hunting Grounds trial marks to enter the Hunters Lodge, she become a fledgling and is able to trade with Aidaba. Aidaba informs Aloy that hunters can give her the marks they've earned at Hunting Trials in exchange for prizes, specifically unique variants of the Blast Sling, Ropecaster, and War Bow.
