Brennanite is an exceedingly rare and highly sought after igneous
rock that many believe not to exist. Its identifiable features include an internal glow that suggests it
may never have or never fully will cool. It is believed to be the finest grained igneous rock out their, which, in direct contrast to its effervescent glow, suggests it must cool impossibly quick to achieve such a structure. The
one known sample is believed to be kept locked in the forbidden 3rd
floor of the Fulton building at the University of
Dundee. Folklore has it that at least 3 students have attempted to sneak up there to find it, only to never return.
