Golden Oak Commoner College was an ancient castle in the Kingdom of Eric. It was not a supernatural college like most, instead it housed and taught the common folk. The place was bustling with men and women walking on the lawn or sitting under trees to study or chat. It always appeared very populated.
However, under the castle there were many secret institutions and labs where alchemy warlocks, wizards, and scholars gathered. There were also theorists, both supernatural and ordinary.
Inside the alchemy gaslight powered underground lab, there were many giant machines, alchemy tables and long iron desks covered in charcoal pencils and papers. For the last century, charcoal pencils had gradually grown more popular until they replaced quills altogether. The young people preferred newly invented ink pens, but charcoal pencils were still the most popular because they were cheap and easy to erase when mistakes were made.
