Pantera was a class IV Mira variable red giant star in the late stages of its stellar evolution, located somewhere in the space of the galaxy's Alpha and Beta Quadrants.
Pantera was surrounded by the vast Pantera Nebula, which was created by planetary remnants caused when the star went nova several thousand years ago.
In 2372, the USS Enterprise-E and the USS Samson was involved in war games inside the nebula. (TNG - Slings and Arrows eBook: A Sea of Troubles)
