The Unarim Tar Pits (pronounced ooh-NAH-row) are a region within Brightmarch where oil, asphalt, and tar seep to the surface. Located in the middle of the fern prairies that cover much of the landscape of interior Brightmarch south of the Ikena River, the tar pits can be a dangerous land. Not only are the pits themselves deceptively difficult to escape, for peoples and creatures alike, but great geysers of oil and tar can erupt from the ground without warning, covering and burning those who do not know to expect them.
Few live in or near the Untarim Tar Pits. Most animals know to stay clear, though in times of drought and at the end of the dry season some still approach in search of water, inevitably trapping at least a few. While most other people give the tar pits a wide berth, the Tar Drinkers live amongst them, using the pits for defense and as a valuable resource.
