Mummy - Pyramid layout explained

I was asked on Lead Adventures if I could give some more details on the layout of my Pyramid. I hope the following explains how the Pyramid works. I sort of made it up as I went along and happily everything seems to function properly for my games.
Percy will be our guide as the danger has passed for the moment. We hope.

Main entrance via ramps

Once the top of the Pyramid has been removed we can see an doorway concealed on the left of the small entrance cavity. Opening this door will release rock balls which will run down the small corridor crushing anyone in the way. The ball will then fall into a small hole which leads down to the lower levels.

Once into the corridor a concealed entrance can be seen in the middle of the dividing wall. (This is opened by removing a small nail and falls by gravity) making anyone standing on that part of the floor fall to the level below which just happens to contain a trench full of Tomb Scorpions or snakes depending on what I have on hand.

View from below which I did not see the need to paint (unfortunately).

Once the Pyramid is removed we can see the Cavern below. I've fudged the ground level as I have not yet worked out a way of cutting out a space in a tabletop.

Now we move outside again to the other entrance concealed within a smaller Pyramid.

We can remove the top of this Pyramid to see the doorway.

This doorway leads by way of tunnels to this doorway in the Cavern below the main ramps, which would be the way the Mummy's followers would use.

Outside again we find a small Needle Monument which has a concealed entranceway used by Tomb robbers.

This leads by way of Tunnels to two holes which have been dug into the cavern wall.

I hope this has been useful for anyone else intending to make something similar. 

I'd love to use this for a Demo game at a convention but since Will moved away I have not found anyone really interested in playing Pulp style games locally.
