On Mergoran crystals…
Magic at this time, though, was primitive and weak, and the only way to use it was to have a power source. That power came from Mergoran crystals, which were discovered and mined in the Lore Mountains, just south of the Anzarin cities in the Halaraan Steppes. The Anzarins, after throwing off their Trohman overlords, mercilessly took over the mining operations of Mergoran crystals, and held a stranglehold over every facet of their use. As a result, the Anzarin leaders in each city, called Clerics, were by far the most powerful and wealthy people in all of Leranon. And power and wealth soon led to corruption, greed and tyranny, all of which the Anzarin Clerics were famous for.
