A laboratory deep beneath the earth which has existed since before earth's demise.
It is the only lab he has that has been able to maintain the peak of technology.
There are a few entrances and exits somewhere within it's complex interior.
It can not be entered forcefully as the scientist has kept his security tight
with the forgotten technology unknown to most of earth's residence.
This lab is powered by numerous elements from sunlight, hard labour to demonic powers.
