At the centre of the Sanctuary is a hole to place your object of worship, you could put some model of your own, (the hole is 4cm or 1.5 inches wide) or buy one of my worshipable models, The Statue of Cthulhu is shown and the other models that fit are the Cauldron of Sacrifice and the Crawling chaos. Supplied unpainted and requires assembly, Cthulhu and investigator are shown as examples and to give you an idea of size.
