The Kothringi were a race of tribal men that once inhabited Black Marsh. The demonym is seen as both Kothri and Kothringi. They are noted for being fierce; and having "metallic skin" and "reflective faces."
The Kothringi were eventually wiped out by the Knahaten Flu that started in 2E 560. By 13th of Sun's Dawn, 2E 561, the Flu had already started affecting even the most remote of Kothri settlements, such as Stillrise Village in Shadowfen. In that case, the Flu had apparently been brought into the settlement from Mud Tree Village, by two trader apprentices named Abaaleb and Sana. Still in 2E 561, Shaman Chirah of Stillrise (under Chieftain Suhlak's orders) prayed to Z'en for a cure for the deadly disease, but had no answer. That led him to appeal to Clavicus Vile, wishing for his village to not die from the disease. The Daedric Prince then turned all of the villagers into undead.
The Kothringi generally preferred to go naked, although a few wore clothes when outside their native land. Their garb, as seen in The Elder Scrolls Online, appears to be simple leather with animal bones stitched in. They lived in round stone huts with chimneys, topped with domed thatched roofs. The triskelion is seen etched into rocks around their villages.
They appear to have had a shamanic society and worshiped a pantheon of their own. Z'en (a god of Toil) was apparently the main god, with Dibe-Mara-Kin (the "mothers of the Around-us") as blessing-givers.[UL 1] In Stillrise Village, Clavicus Vile was worshiped as a last resort against the deadly Flu.
The most well known member of the Kothringi Tribe is Zuuk. He is mentioned in the book series 2920, The Last Year of the First Era. Zuuk was a servant/guard of the Imperial mistress of Reman Cyrodiil. As seen in The Elder Scrolls Online, by the second era, a Kothringi village Zuuk located on top of an Ayleid ruin was named after him.
The last living member of the Kothringi was Drillk, who was apparently royalty. In The Elder Scrolls Online, the Vestige has the choice to either let him live on as the last member of his people, or end his life for the sake of absorbing a keystone to further the cause of the Ebonheart Pact in Shadowfen.
The Vestige learns that the village is divided between those who would like to end the curse and gain final rest, and those who would like to keep living despite the curse's disadvantages. They turn to the Vestige to decide their fate.
Names of the undead Kothringi denizens of Stillrise Village include:
- Chieftain Suhlak
- War Chief Helushk
- Shaman Chirah
- Acolyte Morag
- The ruins of their civilization are shown to Decumus Scotti in The Argonian Account, Book IV 
- It is known that at least some of the Kothringi were sailors. In Varieties of Faith in the Empire, it says the Bosmeri god Z'en is the "god of payment in kind. Studies indicate origins in both Argonian and Akaviri mythologies, perhaps introduced into Valenwood by Kothringi sailors."
