Human: Please generate a brief description of a eerie scene inside a tower with columns, alabaster, sandstone squares, and a floor. Assistant: 
Zigzagging serpent etchings coil their way down a pair of solid alabaster columns that ominously loom over the lofty room. A vast expanse of pale sandstone squares repeats across the floor, leaving the section of the hallway completely void of any other notable ornamentation.
