Centurion's Sanctum

High above the Arctic Circle, on Baffin Island, sits the long-unused secret hideaway of earth’s greatest hero, The Centurion. It served as his home away from home and headquarters, an isolated place for trophies and storage for hazardous items recovered during a lifetime of adventure. Dubbed “the Sanctum,” only a few trusted friends and allies visited it during the Centurion’s lifetime.
After the death of his wife Laurie, Centurion made the Sanctum his full-time residence, bequeathing it to the Freedom League after his death. The League made it a seldom-used secondary base, maintaining it as a memorial to their old friend. Recently, Centurion’s daughter from an alternate timeline, Centuria, was given command-level access and the Centuritrons have been programmed to recognize and obey her. The only Canadians who know about the Sanctum are R.C.M.P. Constable Andrew Enuaraq and his daughter Dorothy; they privately protect the area from the overly curious.
The Sanctum is buried deep beneath the arctic ice, with a tunnel leading to a massive metal hatch (constructed from an alien alloy) covering the front entrance. The hatch weighs 200 tons and is extremely strong. There is a secondary tunnel, leading to the cliff face of nearby Mount Thor, that can only be accessed if the Sanctum itself is in danger of destruction. The Sanctum contains a great hall, a menagerie of alien animals rescued from the Curator, a memorial to Centurion’s lost home world (including the original dimensional pod that brought him to Earth), a trophy room with mementos of past cases, and an arsenal of confiscated weapons and devices. The “cyber-city” of Tronik is contained in a computer module in the Sanctum. A monitor room equipped with viewing screens can display world media broadcasts, and there is a teleportal accessible from the Freedom League's satellite headquarters, The Lighthouse.
The Sanctum also contains a featureless white chamber called the Zero Room. It can transport things to and from the extra-dimensional Zero Zone. The Centurion used it to imprison threats to humanity so great they could not be entrusted to the conventional authorities. The Freedom League has only used the Zero Room twice since taking over the Sanctum, first to imprison the Alpha-Centurion, and more recently against the alien Ultracide Nox, a telepathic leech that attempted to drain the mental capabilities of every individual on earth (overcome by a temporary alliance between the Freedom League and their arch-enemies in the Crime League). The Freedom League keeps the Zero Room in reserve, unbeknownst to anyone else, although they have debated the possibility of shutting it down altogether.
TRONIK, THE CYBER-CITY During one of Centurion’s encounters with the Curator, the alien computer intelligence “saved” the human inhabitants of an Earth-like world by digitizing the memories and intellects of the entire population of the city of Tronik. Millions of people were reduced to optical data stored in an advanced, compact computer simulation of their previous environment. Centurion rescued the Troniks from unending stasis, but had no means to physically restore them, so he kept the storage module for their data, an alien computer the size of a briefcase, in his Sanctum, running continuously.
The Troniks are unaware of the true nature of their existence, and Centurion chose not to tell them, out of concern for the psychological harm it could cause, to know they were no longer “real,” just virtual copies of real people. The virtual world in which they live is such a perfect simulation that the inhabitants of Tronik believe they escaped the cataclysm that destroyed their home world and founded a new city on an uninhabited planet they call Neo.
Tronik’s technology is similar to that of the Lor Republic. It is a city of soaring towers, connected by sky bridges and anti-gravity lifts. Energy weapons, force fields, and similar technology are commonplace. Although none of it is real, Tronik’s “technology” is based on how the real versions once operated.
A virtual reality interface in the Sanctum allowed Centurion and others to visit Tronik, and Centurion maintained a “secret identity” there. Visits to Tronik are risky simply because the “rules” of the virtual environment prevent any super-powers from functioning, so visitors are effectively normal humans. Despite the fact that Tronik’s environment isn’t “real,” biofeedback from the virtual system can induce fatal shock and other damage to visitors, so threats there are more than real enough to outsiders.
Since Centurion’s death, the Freedom League has looked after Tronik, allowing the Sanctum’s automated systems and the Centuritrons to care for it. They have visited the city on occasion to check on the status of the inhabitants and to address problems or faults in Tronik’s virtual program, but have otherwise continued to keep the secret of Tronik’s true nature and allowed its inhabitants to go on leading normal lives, unaware their world is confined to a small box sitting on a counter.
