The Osarel Mining Company

The Osarel Mining Company is the largest arcane crystal extractor in the Aristocracy, with business shooting out to foreign shores as well. 
Headed by the Osarona and the Zumrel family out of Dragonsden in Al'Muhar its still a family owned business 250 years later with the matriarchs that started it still working there. 
The start of the company was based around the original rush of companies moving to extract the large quantities of arcane crystals in dragons den that bolstered their military and economy to a world power. After mining was halted in dragons den for fear of breaching the walls and letting the waters around Al'Muhar flood dragons den like in 1403 when a mining company flooded dragons den for a full month because they did so themselves. They now also have other mining operations they handle as well as experimental works on arcane engine development.
