The T:DS Castle area is a combination of the Castle Front and the Inner Quarters.
The colored map was created with the Castle Front as the base(south) and the Inner Quarters(north) attached via two vertically parallel gateways in the central tower.
Alignment is based on the orientation in T3Ed and the in-game compass of the Castle Front only(up is north).
The Castle Front map has one flaw, the moon is located to the north(impossible) and the interior moon beams are from the east(an improperly aligned sky box).
The Inner Quarters map is aligned east to west(tower to tower) in T3Ed and the compass was adjusted to point north(west or left) in T3Ed. The map needed to be rotated 90° clockwise so that up is north. The moon in this section is in the east with the moon beams coming from the east(compass wise in T3Ed). Sky box alignment was consistent for this section.
