According to the legends of the Mentarn clan, the silver-studded halls of Mentarn were first excavated not by Dwarves but by a great silvery dragon. Thousands of years ago, the Dwarven prince Obeag lead an army of Dwarves to end the depredations of the dragon, defeated it, and took the halls for their own.
There is a strong bond between the Dwarves of Mentarn and the Elves of the Long Lakes which, while rarely needed, has never been broken.
The deep center of the Halls of Mentarn, to which all caverns lead, is the great clear lake of Megrion, where the bones of the dragon sank on its defeat. Great silver and crystal arches encircle the lake, leading both up and down to the various halls of Mentarn, and a deep white light infuses cavern reflecting the silvery roof in the still waters of the lake.
