Argonian

While Argonians appear reptilian in nature at first glance, they also exhibit qualities of fish and amphibians: they are able to breathe underwater through small gills behind their ears, and swim using the same method as that of a tadpole or eel by moving their tail side-to-side to propel through the water. Argonians possess the most alien personalities in all of Tamriel from a human or meric perspective and it is often assumed that Argonians possess neither personality nor emotions. Of course this is not true; Argonians simply do not facially express their emotions as much as man and mer do, though anger is easily detectable from their bared teeth and narrowed eyes. Argonians' genders are sometimes referred to as life-phases, implying they may be able to change gender. However, this is unconfirmed, and Argonian hatchlings may be of either gender.
History The earliest historical records suggest that the Argonians were already present in preliterate tribal communities when the Aldmer began exploring Tamriel, and that no man or mer could survive in their fetid, septic environment. This proved untrue, as members of a surprising amount of races and cultures inhabited Black Marsh over the years, and the province remained relatively peaceful until the Second Era. Of course, the other races didn't know what to make of them; they were perceived as everything from curiosities to heroes to monsters. Some of them began venturing out into other parts of Tamriel in the First Era, and proved surprisingly adept at assimilating into other cultures. Pirates began using Argonia as a base to Attack rich merchant groups in eastern Cyrodiil, leading the Alessian Empire to launch an anti-piracy campaign in 1E 1033 that took them deep into the heart of the swamps, where they encountered heavy resistance from the Argonians (who, thanks to their experiences with the pirates, had developed a deep distrust of outsiders). They were quick to leave once the pirates had been dealt with. Argonians wouldn't be brought into the Imperial fold until a year after their defeat in the Battle of Argonia in 1E 2811. The Empire, which could only really govern pockets of the province along the coast and borders given the harsh interior, used it as a prison for the worst of criminals who could not be trusted in conventional dungeons. During the Interregnum of the Second Era, in 2E 560, a mysterious and lethal flu broke out which killed virtually every non-reptilian race.
Saying Tiber Septim conquered Black Marsh is a bit of an overstatement; he gained control over the borders and major population centers along the coast, but he wisely avoided trying to assert control over the interior. He would once again use the province mainly as a place for high-security prisons. Unfortunately for the Argonians, the very traits that enabled them to survive so well in the swamps of their homelands also made them ideal slaves for hard labor in regions of Morrowind that would prove unbearable to other races. During the Interregnum, bandits once again roamed the province in large numbers and entire tribes of Argonians were enslaved. In 3E 396, during the Imperial Simulacrum, a slave revolt escalated into the Dunmer instigating
the Arnesian War with Black Marsh and taking a significant amount of territory (and undoubtedly many new slaves). Along with the Khajiit, Argonians, particularly in eastern Tamriel, carried the constant risk of being kidnapped and enslaved. Though enslaving any civilized race is illegal in the rest of the Empire, the Dunmer of Morrowind had practiced it since time immemorial and continued to do so even after joining the Third Empire, despite the disgust and frustration of many people throughout Tamriel. This was due to the favorable conditions of the treaty under which Morrowind joined the Empire, which allowed the Dunmer to follow their ancient traditions and maintain great autonomy in their domestic affairs. King Helseth eventually abolished slavery in Morrowind for a wide variety of reasons. The abolition of slavery improved relations with Morrowind, but Argonians did not forget the transgressions of the Dark Elves. The ramifications of the arrival of the Nerevarine, especially the loss of their living gods, left the Dunmer very weak at the beginning of the Fourth Era, and the Argonians had emerged from the Oblivion Crisis more unified, stronger and ambitious than ever before. Taking advantage of the eruption of Red Mountain that weakened Morrowind, they successfully and ruthlessly invaded mainland Morrowind, driving the remaining Dunmer out of their ancestral homeland and onto the small island of Solstheim and across Tamriel. Society and Religion Argonians usually live in tribes, each having their own customs as well as differing appearances. They worship (or at least, deeply respect) the Hist. Some early sources suggested the Hist were an ugly and frail breed of Argonians, but other more reliable sources have since revealed that they are a type of ancient, sentient tree native to Tamriel that Argonians cherish, and that the trees secrete a type of sap-like resin that hardens and can be sculpted into an ideal Armor. In addition, Hist sap can be violently hallucinogenic when ingested. The Argonians apparently believe that the Hist have given them their souls and that when they die, their souls are returned to the Hist to be reincarnated as a new Argonian. They feel a connection to the Hist when in the Black Marsh, but this diminishes with distance. When an Argonian makes physical contact with a Hist tree, it may communicate with them through visions. The economic system and way of life amongst Argonians in Black Marsh is seen as "backwards", as they mainly farm, fish and hunt for subsistence and have only recently seen fit to start interprovincial trade. Like all the odder-looking races, the Argonians experience quite a bit of prejudice and hostility even from people not trying to enslave them. Their native language, Jel, involves many grunts and squeaks, and the intricacies and rationale of their naming conventions are completely unknown to outsiders.
