1 The floor of the church is the roof of a very old crypt. The crypt is full of the remains of bodies, all well preserved in the cool, dry environment. All the bodies show signs of being bled to death.
But one of the bodies is not yet dead, and after such a long sleep it is very thirsty.
2 Further information comes to light in original translations of the Bible. The place is very unholy indeed, devil worship was actively carried out and only after the place was cleansed was the church built. A ward against evil (similar in design to similar wards found on Neolithic megaliths) has been carved upon one of the flagstones, but it has been removed by the University for study.
Without the ward, it is only a matter of time before evil returns.
3 Removing the flagstones reveals a narrow, unpleasant tunnel. Entering the tunnel reveals a complex of narrow, winding passages. Although clearly ancient, the tunnels are structurally sound and are relatively safe to explore.
When mapped, they form a strange twisting complex of no obvious design. And despite clearly having been constructed long before the modern city above, they loop around foundations, sewers, pipelines, and other modern contrivances as if the original builders knew to avoid them.
They, and their builders, are a complete mystery.
