Additionally, the city's secluded position protects it from various weather conditions such as rain. The gothic-style architecture of the city is ornate and intricate, and the large buildings and infastructures within the city produce light through illuminating lux blastia. Long, winding staircases connect the differing levels of the city, including the entrance to the city, which is frequently guarded by the Imperial Knights. The only accessible inn and shops are located in the city's vast library.
