Upon meeting with Riju at the Lookout Post, she will tell Link of her plan to take down Naboris. Before leaving, she mentions that the only way to get close to Naboris is by riding a Sand Seal. After successfully returning the Thunder Helm, Riju dons it and instructs Link to meet with her at the Lookout Post south of Gerudo Town. Interested by Link's offer, Riju informs Link that her precious heirloom, the Thunder Helm, was stolen and tasks him with retrieving it from the Yiga Clan Hideout.
In order to stop Naboris, Link must enter Gerudo Town and seek counsel with Riju, the Gerudo chief, and offer to quell it. Overview Breath of the Wild Entrance to the Divine Beast
