Enigmatic and intelligent, the Argonians are experts at guerrilla warfare and their natural abilities suit their swampy homeland. They have developed immunities to the diseases that have doomed many would-be explorers in the region, and they are capable of easily exploring underwater locations due to their ability to breathe water. Argonians make proficient thieves, due to their increased lockpicking and sneaking skill.

After conquering the Dunmer province of Morrowind following the eruption of Red Mountain, little is known about the politics of the Argonians in the Fourth Era. There is an Argonian political faction called the An-Xileel, but there is little infomation about them, except they're composed of mostly, if not all, Argonians, and that they pushed back Mehrunes Dagon's forces during the Oblivion Crisis in Black Marsh and were the faction responsible for orchestrating the conquest of Morrowind.

Unlike the citizens of Skyrim who prefer to marry using an Amulet of Mara, some Argonians adhere to their native marriage traditions. In Black Marsh, it is customary to present a lover with an Argonian Wedding Band, which is crafted by the courting member. Each ring is unique and has personal meaning to the creator and the recipient.
