The Ulath Tribe (also known as the Ulathi) is a minor Ashlander tribe that lives in the Stonefalls region of mainland Morrowind. Little is known of them, as they are hostile to outsiders. The Cave of Memories, a small cave northwest of Heimlyn Keep, serves as their ancestral burial grounds. They are particularly devoted to the Daedric Prince Mephala, one of the Three Good Daedra, and make silver armlets fashioned in the semblance of a spiderweb to honor her.
The Undaunted are a faction of dungeon-delving adventurers who set the scene for each of the Group Dungeons and Trials that can be found in the world. The locations of each of the base-game dungeons can be discovered by talking to Undaunted members within the tavern in the main city of each zone, while DLC dungeons become accessible upon unlocking the related DLC. Note that all dungeons and trials can be traveled to directly from a Wayshrine once you have learned their location. The Undaunted skill line focuses on group utility, and provides skills which aid allies in group combat as well as dealing wide-ranging damage. All of the abilities give the opportunity to activate synergy. To gain reputation with them, you must complete Dungeon Achievements (not including those in the Public Dungeons section), Pledges and delve dailies.
The Urshilaku Tribe is a tribe of Ashlanders living in Vvardenfell. Their camp is in the West Gash region, not far north of the city of Gnisis. Like the other major tribes, they have sent some of their members to Ald'ruhn.
