I don't think one shaman can pull it off - at least not in one try. Remember that cult in San Diego that offed themselves because they thought the Hale-Bopp comet was a starship coming to pick them up? When that house was finally sold, the new owners had the house torn down, the foundation ripped out and then they brought in an assortment of holy men (rabbi, priest, imam, monks, etc.) to spiritually sweep the place clean.
btw - congrats, Chernobyl!
