I was now standing inside a narrow dungeon corridor. On my left was a high gray cobblestone wall with a mammoth dragon skull mounted on it. The wall stretched up and up, vanishing into the shadows above. I couldn’t make out any ceiling. The dungeon floor was composed of floating circular platforms arranged end to end in a long line that stretched out into the darkness ahead. To my right, beyond the platforms’ edge, there was nothing—just an endless, empty black void.
