In Blood Ties, what counts as a room boundary for the purpose of Horror Tests and Item Abilities? (e.g. Elder Sign)
For example, my girlfriend raises a zombie in the graveyard. Do all my investigators out in the open have to take a horror test, or only those in the graveyard?
Alternatively, Gloria Grant is surrounded by 4 zombies, all within 1 range. Does her successful Elder Sign roll drive all the zombies back, or only those that are on her tile?
