maybe I will try to get in again and tell them I made it. I'll edit this post with the screens but first I want to make a diagrammatic map
the diagrammatic map, followed by a roughly representative axonometric:


the bottom wing, making the base of the cross, was to be deeper than any of the other wings and twice as wide, with stairs alternating on each wall. I had a good deal of it completed, but I apparently didn't take any screencaptures of my work in that wing.

an inconspicuous entrance resembling a hobbit barrow.

this is the top floor of the top layer, ie the transept of the cross. we are in the middle of the transept where the two upper sections connect. behind us is more catacombs and the passageway to the mickey chamber.

Mickey, our king, in all his glory. I had intended to gild this room.

this is the middle layer of catacombs, looking from the top balcony of the stairwell. this is really poor representation of the depth and length of the space though at the middle of the image, right below the crosshair, you can see part of the entrance stairway into the lower catacombs. the stairway above the crosshair leads too the upper catacombs, and is accessible via the ledge you can see on the right.
the bottom layer was about as deep as this, and I intended to make it go even deeper. it was also twice as wide, providing more open space and a better sense of scale. more rooms were planned as can be seen on the diagrammatic
