Glitterdelve Mine was the massive mine at the town of Glitterdelve and was the source of most of Ehb's wealth. During the Seck Resurgence , it was overrun by Krug , and it wasn't until Lady Montbarron and her band from Stonebridge liberated the town and the mine.
The Krug had housed their command in the mines, as they were the safest place to do so.
This mine was smaller than the Crystwind Mines, but as it was closer to Ehb, it was more advanced in terms of mining equipment. This included a repair bay for minecarts, and lots of elevators.
