Im pretty sure theres gonna be cults devoted to the different gods:
Nordic Gods
Alduin
(World Eater) Alduin is the Nordic variation of Akatosh, and only superficially resembles his counterpart in the Eight Divines. For example, Alduin's sobriquet, 'the world eater', comes from myths that depict him as the horrible, rauaging firestorm that destroyed the last world to begin this one. Nords therefore see the god of time as both creator and harbinger of the apocalypse. He is not the chief of the Nordic pantheon (in fact, that pantheon has no chief; see Shor, below) but its wellspring, albeit a grim and frightening one.
Dibella
(Goddess of Beauty) Popular god of the Eight Divines. In Cyrodiil, she has nearly a dozen different cults, some devoted to women, some to artists and aesthetics, and others to erotic instruction.
Orkey
(Old Knocker) A loan-god of the Nords, who seem to have taken up his worship during Aldmeri rule of Atmora. Nords believe they once lived as long as Elves until Orkey appeared; through heathen trickery, he fooled them into a bargain that 'bound them to the count of winters'. At one time, legends say, Nords only had a lifespan of six years due to Orkey's foul magic. Shor showed up, though, and, through unknown means, removed the curse, throwing most of it onto the nearby Orcs.
Tsun Extinct Nordic god of trials against adversity. Died defending Shor from foreign gods
Mara
(Goddess of Love) Nearly universal goddess. Origins started in mythic times as a fertility goddess. In Skyrim, Mara is a handmaiden of Kyne. In the Empire, she is Mother-Goddess. She is sometimes associated with Nir of the 'Anuad', the female principle of the cosmos that gave birth to creation. Depending on the religion, she is either married to Akatosh or Lorkhan, or the concubine of both.
Stuhn
(God of Ransom) Nordic precursor to Stendarr, brother of Tsun. Shield-thane of Shor, Stuhn was a warrior god that fought against the Aldmeri pantheon. He showed Men how to take, and the benefits of taking, prisoners of war
Kyne
(Kiss At the End) Nordic Goddess of the Storm. Widow of Shor and favored god of warriors. She is often called the Mother of Men. Her daughters taught the first Nords the use of the thu'um, or Storm Voice.
Jhunal
(Rune God) The Nordic god of hermetic orders. After falling out of favor with the rest of that pantheon, he became Julianos of the Eight Divines. He is absent in modern Skyrim mythology.
Shor
(God of the Underworld) Nordic version of Lorkhan, who takes sides with Men after the creation of the world. Foreign gods (i.e., Elven ones) conspire against him and bring about his defeat, dooming him to the underworld. Atmoran myths depict him as a bloodthirsty warrior king who leads the Nords to victory over their Aldmeri oppressors time and again. Before his doom, Shor was the chief of the gods. Sometimes also called Children's God (see Orkey, above).
Ysmir
(Dragon of the North) The Nordic aspect of Talos. He withstood the power of the Greybeards' voices long enough to hear their prophecy. Later, many Nords could not look on him without seeing a dragon.
Herma-Mora
(The Woodland Man) Ancient Atmoran demon who, at one time, nearly seduced the Nords into becoming Aldmer. Most Ysgramor myths are about escaping the wiles of old Herma-Mora. Also called the Demon of Knowledge, he is vaguely related to the cult origins of the Morag Tong ('Foresters Guild'), if only by association with his brother/sister, Mephala.
Mauloch
(Mountain Fart) Orcish god of the Velothi Mountains, Mauloch troubled the heirs of King Harald for a long time. Fled east after his defeat at the Battle of Dragon Wall, ca. 1E660. His rage was said to fill the sky with his sulphurous hatred, later called the "Year of Winter in Summer".

it will also be interesting to see a cult for Shor as we don't get to see much on Lorkhan
