This map was sketched by Mile's father Evroult Patris d'Areyn, capturing his recollections of the layout of the Old Hall, the ancestral home of the House of d'Areyn.
It was given to Mile when it became clear that the forces of the Iron Crown were determined to recover the Dragonbowl for themselves, and that Mile would need to stop it falling into their hands.
As well as a sketch showing the general layout of the different levels within the Halls, Evroult added some notes on specific locations and hazards, although he did not remember enough to add further detail on the layout of rooms and other features. However he did mark the last known location of the Dragonbowl, and the East Stair, which would permit access to a higher level of the Halls by climbing the cliff face between two waterfalls.
