The ground floor of the cylindrical building was at least twenty storeys below their vantage point. Painted on the floor was an ornate compass design. In the centre of the compass, Isla could just make out a figure sitting on a spindle-backed chair. There was a wide carpeted ramp that hugged the wall and twisted all the way up to the platform. Along the length of the ramp, on every level, were rows of doors lined up like dominoes. Some were plain while others were painted with intricate multi-coloured designs or ornately decorated with inlaid stained glass. Many of them looked to be damaged or in disrepair. Several had large chains or ropes zigzagging across them preventing access.
