The fortress of Kal'Hirol was established by Paragon Hirol and became known as a center of learning for smiths. Its workshops are where Paragon Hirol conceived his famous improvements to golem resilience and power, and where Hirol's favorite student developed a method for storing refined lyrium that is still used today. These breakthroughs brought Kal'Hirol great prosperity, its passageways glittering with gold and silver. For decades, the thaig was the favored home of apprentice smiths. Unfortunately, as time wore on, only the richest could afford to train there.
