Dragons of Frosthold
A remnant of the Deregonian Empire, built on the shores of the frozen northern continent as a naval port and trading post. After the fall of the Deregonian capitol the second prince Lellouche Deredon fled with his escorts to the city seeking safe haven.
After word got out that Frosthold was a safe haven for all Deregonians ships flooded in overwhelming the already modest city. Elven and dwarven engineers went to work expanding the city immediately. The dwarves dug deep building a city beneath the city and the elves built a floating island suspended by magic towers that also act as a barrier to protect Frosthold. Three cities built on top of eachother the largest city in the world and the last remnants of one of the greatest civilizations since the time of dragons.
