Snehk's Dreamlands

I was a priest in a chapel of some kind of elder god. It was in old, victorian village. The chapel itself was built from marble, granite and gold, stylised as a gothic cathedral with baroque elements. The altar was really high, it had a fountain of purifying water on top of it. There were also channels carved within it, so if priest opens it, the water can flow. I was a new priest there. I thought about making a challenge, and it was about shooting the highest possible with a catapult. Only a few could accomplish it, and if they don't they would evaporize. The reservoir went dry, and I had to go a long way to get a huge cistern with purifying water.
