If Acrostic was actually "A Cross Stick" we could have a biblical themed house, or something to do with Lords of Salem. The Evil Dead does sound very probable though. Also, just looked it up on a whim but alters to Barron Samedi usually contain crosses, so Esquelto Meurte or Voodoo could also be a possibility.
Any ideas on why the house changed? And what was the consensus on what it was before?
