I'm not, but if I entered, I see something as simple as a fortress, palace, temple (?) in pristine "in use" condition, then 800 years later as a haunted, abandoned site. Would work for a storyline like, the adventure party ventures into the haunted ruins at such and such place, encounters a ghost who desires freedom into an afterlife, he needs an item that was lost on the day of his death to be buried with his bones. A related artifact is hidden in the ruins that will help the party find the location of the missing one. Upon touching the artifact, the party enters a temporal wake and instantly go back 800 years to the day of the murder of said ghost. Now they have a day of investigation and adventure to aid the final death of the protagonist spirit.

Most of Ascension's ideas suggest expansion of dungeon/city/empire which I hadn't even considered at the idea of the challenge. Again, anything applies! I look forward to see some entries soon.
