Thundercrest

During the Great Expanding, three Dwarven clans journeyed from Ginnungagap in search of new treasures and lands to innovate in. Thindercrest, being the closest to Ginnungagap, was first to be established officially. It was built in an unlikely place for a Dwarven city, for it was placed directly in the center of an open field. The ingenious Dwarf leaders of the time has a natural sense of where riches would be buried, so despite the odd location they pushed on. And what a beautiful city was made. They dug straight down and made Thundercrest an almost entirely subterranean civilization. By all accounts of the time, Ginnungagap itself could not make a finer city to live in.   Many years after, in the midst of the 500 Year war (which Thundercrest abstained from) Dwarven miners stumbled across a massive cave system beneath their city. The discovery of these caves released a wave of dangerous gases. When these gasses reached the torches used by the Dwarves, they ignited resulting in many explosions in the mines underneath the city. The mines collapsed into the newfound caves, and swiftly, the city into the mine shafts. This killed most of Thundercrest's denizens and left a crater in the earth where the city was originally hidden. The few Dwarves who did survive were displaced, most returning to Ginnungagap.   The gravity of this grievous disaster weighed heavily on the Dwarf kings of the time. Obviously, Thundercrest could not be rebuilt, so the best they could offer was building a shrine to remember the lost clan. They constructed a statue in the name of the goddess Berronar Truesilver. Modern Dwarves are now superstitious of the area, believing it to bring bad luck just by being near its vicinity.
