How can you make someone look possessed? [3.5]

[Scarey Nerd]

How good are you at getting things pinned on them? Can you commit evil acts and make them look like they're done by your targets? Also don't forget using magic like dominate person etc. to make people react to a fake "magic circle against evil" or somesuch.

Also, how many people are there around that might have decent knowledge religion? You can always make up a symptom of possession that one of your casters can induce in people.

In the next session our plan is to mark the bodies of the "possessed" in such a way as to make them seem strange. My idea is to ask to study the bodies alone, then take the eyes out and cut the optical nerve, then replace them back to front, then get the wizard to cast Arcane Mark on the eyeballs.

This is a heavily religious city, with worshippers of Pelor and Heironeous, but we can most likely get around that as we have an NPC archivist in communication (My backup character coincidentally) who has studied such things for his entire life.

Also, we can most likely pin crimes on people, go into a house and kill a family, leaving the teenage son as the only survivor and probably insane after witnessing our acts.
