In the wake of the last great parts war, there was a building which was used for the wholesale research and manufacture of AT parts and specifically Regalia. In Kyoto this factory was nearly demolished and thus abandoned in the wake of some very mysterious circumstances. The skeleton of this building is slowly but surely be reclaimed by nature and is covered in moss and even a sprouting trees. It is the perfect high rise and complicated location for advanced training and an interesting venue for parts wars.
