Greetings, fellow GM
while brewing up some ideas for Laughing God (who sadly happend to drop his request post into the wrong forum) I started to wonder a little about the DotG-adventure "House of Dust & Ash". (SPOILER SPOILER SPOILER)
After it is on, it assumed that a lot of NPC escape the auction site and that their is some cat and mouse game going on in the halls and corridors of the completely unlocked (but locked in regard to the outsight) House of Dust & Ash.
...but how shall the PC & NPC hunt each other? The building, the floors and halls are made of stone (as far as I get it!). This is not a material one leaves footprints on. Since no real map is given and the only determined points of interests are the auction site and the entry hall containing the Haarlock Tomb it will be hard to make the NPC & PC zick and zack about the site since in the mind of the players their are only the two points of interest the GM has established.
Any idea how this could be changed? The possibility of running all of the events after the auction as "change encounters" is not appeling to me. Had anyone used the "pre-auction time" to allow the players to strole about and familiarise themselfs with the general area?
