At a glance, the assembly room seemed to be the most important room out of all the ones inside the facility, though that statement is not false, it was also not true. The whole place was built in a way so that the assembly room was situated at the bottom end and kept isolated from the rest of the facility.
It was not only the most important place, but also the most dangerous place. The thousands of test subjects that have been kept inside the frozen wall for hundreds of years, were not actually dead.
Since each of them had been transplanted with precious materials that were too good to throw away, they brought over a powerful ice mage to create this advanced spell [Frozen Coffin] to keep all of them in a state of suspended death.
