Human: Generate a eerie scene inside a mansion with tapestries, glass, and undead. Assistant: 
Huge leathern tapestries hang on the walls of this arched-ceiling hallway, painted in vivid and unsparing detail. Each one depicts a macabre scene, from a hoard of ravaging undead to a tall man tearing open a hole in reality itself. Stairs leading upward are blocked off with a thick pane of glass marked with a crimson rune, denying passage to the upper parts of the manor.
