Chasm

The chasm as the name implies is a large hole under Zenith (City) which helped to protect it during the calamity. This chasm has proven next to impossible to measure thus leading to some theories that there is no bottom. This is unproven though.

There are stone hands that rise out of it and hold up the bridges to Zenith. They are only able to be controlled by the Zenithean council.
