Zion was a real gem in the Archangels' crown. Anybody who was fortunate enough to get into the city could not argue with that statement. The Temple was amazing - a true work of the archangels themselves, with all of its 'magical' properties.
For all that, however, Zion and the Temple were a place of corruption and evil.
Tellesberg was not that majestic - it was a city of merchants and workers, a city of sailors and fishmongers. Built only and solely by the hands of men. Its Cathedral was beautiful, but not magical. Yet it was the truer House of God.
