After completing the main quest: Camera Work in the Depths? and unlocking the camera feature and the Hyrule Compendium in Purah's Pad, go and have a chat with Purah.
In order to progress in the main story and find clues about Princess Zelda, Purah will ask you to investigate the 4 calamities located in the 4 regions, and the Rito Village in the Hebra Region seems to be the first place you should visit.
As mentioned by Purah, each region of the world has a Tower, so don't hesitate to visit them to unlock a fast travel point, which will make your travel easier.
Following your discussion of the regions with Purah, head for Rito Village in the Hebra Region, northwest of the map, as recommended by Purah.
