Hilda, a fierce warrior of the Kalah tribe, initially confronts Prince Kelby and his guardian Odin as an antagonist during their journey to Gara's Keep. Recognizing them as Boticans, she attacks with her soldiers. Though Odin defeats her in combat, she destroys the remaining Botican robots during the fight. Kelby intervenes to spare her life, taking her prisoner against Odin's objections.

Her deep-seated resentment towards the Kingdom of Botica fuels her hostility, stemming from its historical military campaigns that inflicted suffering on her people. As a captive, Hilda evolves from prisoner to reluctant ally, journeying with Kelby and Odin. Her presence forces Kelby to confront Botica's oppressive legacy, challenging his previous understanding of his kingdom's history.

After gaining the group's trust, Hilda later betrays them, aligning with Locke's forces during the assault on Gara's Keep. She ultimately redeems herself by sacrificing her life to shield Kelby from a fatal blow, completing her transformation from adversary to protector. Her knowledge hinted at other tribes and factions opposed to Botica as potential allies for Kelby, unexplored due to her demise. She wears distinctive red armor.
