Daria isn't the Nerevarine (or a Dragonborn). The series' emphasis is definitely NOT on epic adventure. The version of Tamriel used is specifically the one described in The First Edition Pocket Guide to the Empire and seen in Tamriel Rebuilt, so central Cyrodiil is still a jungle. Others have had their names altered to fit in Tamriel (the names from the show will be used for this entry).
Daria, Jane, and their respective family members have the same names they do on the show. Nearly all of the characters from the show make an appearance. Most are told from Daria's perspective, but Quinn, Jane, Sandi, and Mack all get a bit of time in the first-person spotlight. The structure is episodic, though later stories build up on the earlier ones. Rather than taking the Trapped in Another World route of isekai, the story instead re-imagines the characters from Daria as being natives of Tamriel (though not necessarily Morrowind) in the late Third Era. Daria in Morrowind is Exactly What It Says on the Tin-an alternate universe fic (contextual reassignment) series that combines Daria with The Elder Scrolls III: Morrowind.
