The former headquarters of the Church was the best-suited building for Arnold and his summons. It had the housing space that could fit over five hundred people in it, there was a constant power supply for them as well (not that they had a need for it), and one of the main attractions were the prison cells that were located at the basement of the building. They were once used to hold the people whom the church captured, but now most of them were empty. Right now Arnold was inside one of these cells.
