Through consultation with Clergyman 2, the PCs had narrowed down the list of suspects to 3 possible parties:
1. The Order of Wisdom from the Earth which have a long rivalry with the Church over followers and conflicting theologies. It was speculated that the theft of the artifact might be an attempt to discredit the faith of the Heavenly Sight. The rumors currently flowing around town on the church angering their own deity and the artifact having been taken back as punishment seem to support this theory.
2. The "Unfaithful One" who was banished and just before his banishment was caught trying to taint the artifact with his unholy stain. While more protection had been put in around the artifact after the attempt, the "Unfaithful One" has his own unholy powers and his familiarity with the church would give him a reasonable chance of success in stealing away the artifact.
3. An overzealous patron of the Church who had expressed his desire to house the artifact in his own mansion in 'proper splendour'. It was clear that he had both the resources and the possible motivation for arranging for the artifact to be stolen.
