There are deeper structures hidden beneath the Archon’s Tower. Those who have discovered these ancient ruins can but assume that The Master at the Table chose this site to build the tower specifically to seal off the entrance. The two-level substructures have their own distinct architectural style, lots of curved corners, a few too many stairs, and a dried pool in the lower chambers that was likely once full of some foul ichor or perhaps even blood.
Of note, there are four ways between the two levels. Two stairs lead down to the main room in the lower level from above, the stairs in the southeast corner, and the broken floor in the chamber on the upper-right that leads to the room just to the east of the central chamber below (with all the debris on the floor from the collapsed ceiling above). The chambers here show that they have been used for other practices over the years, with tables set up here and there for guards or perhaps even living.
And of course, the oracle did indicate there were important lost treasures down here…
The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 10,800 pixels (36 squares) wide. To use this with a VTT you would need to resize the squares to either 70 pixels (for 5′ squares) or 140 pixels (for the recommended 10‘ foot squares) – so resizing the image to 2,520 pixels or 5,040 pixels wide, respectively.
