The Greyhold. The heart of darkness for my popular antagonistic force. A stronghold moored to a flying island, propelled with smoke-belching jet engines and a wormhole-opening beam on the underside. Inside the impregnable building, the generals of the Greys collect and devise new and devious schemes to rule the multiverse! Truly, a proper evil fortress, as far as evil hideouts go.
