In 59 NE, a number of long running planetary survey missions, that had been fully funded by the Council to locate a suitable planet to host the Wargames, finally concluded. Some of the submissions barely met the criteria laid down by the council, with such lack of effort making clear that it was a simple cash grab by the survey operators involved.
Of the five that were deemed viable and appropriate, three where eventually rejected on subtle technicalities and of the remaining two, Entropy was finally chosen due to the improbably high proportion of landmass that was comprised of islands and island clusters, each with a total area under 5,000 square kilometres - making them ideal battlegrounds. Thus, six years later, the ECZ was born!
It was not long after this that Titan Corporation commissioned a large orbital in equatorial, geostationary orbit around the planet. This would serve as an operational command centre to oversee the prodigious amount of technology required to manage the games and reset the environments at the conclusion of a conflict. It would also serve as a staging post for the raft of support subsidiaries that would inevitably be attracted to such an environment as well as providing crews and operational staff with accommodation, R&R facilities, and a wealth of illicit activity that seemed to attract very little effort to eradicate.
As it is predominantly the same set of islands on Entropy that are continually reused for the wargames, Titan Corporation took the decision early on to see the substrate and upper bedrocks of these islands with a classified active nano technology. This, combined with their industrial replicators, is capable of restoring any given island to its former glory upon the completion of a given campaign.
Depending on the size of the island and the extent of the damage inflicted to the landscape through the course of the engagement, the restoration process typically takes between a few days and a week. In rare situations where the schedule is particularly tight, teams may encounter remnants of past battles that have not been cleaned up before the current battle had to start. These abandoned structures can often hold a wealth of valuable information but also tend to attract the larger native wildlife as they provide refuge from the elements. They should be approached with caution...
Titan Corporation released a declassified interface to this subsurface nanotech to allow the deployment payloads to also leverage it to reshape the terrains and provide solid foundations for the facilities and outposts to be constructed on. Early attempts to create these structures using the direct matter conversion and tactical geothermal tethers alone yielded structures that were unable to withstand the rigours of combat to a satisfactory level.
