A humanoid people with a matriarchal society whose mining colony of 3,600 on Paraagan II was wiped out in 2152 when its tetrazine-laden atmosphere ignited during a visit by Enterprise NX-01.
The Paraagans are a humanoid species who maintained a mining colony on Paraagan II. Their society is described as matriarchal, and they had invited Enterprise to visit after earlier contact with the Vulcans.
In the episode Shockwave, the colony's mining produces tetrazine in the upper atmosphere, so visiting craft must close their plasma ducts before descending. As an Enterprise shuttlepod approaches, the atmosphere ignites and every one of the 3,600 colonists is killed. Starfleet and the Vulcans blame Jonathan Archer's crew and the mission is recalled.
With information from the time traveller Daniels, Archer's crew raid a Suliban stealth cruiser and recover data proving that the Cabal planted a device on the shuttlepod to cause the explosion, clearing Enterprise in Shockwave, Part II.
