The Year 2099 - One way of protecting clients of older urban dwellings against the increasing air pollution and heat was to create giant encasings for lower built structures. This however was seen as a makeshift-measure as these 'spaces' conveyed an air of sovereignty, sometimes even 'autarchy'. In most cases the 'hangars' were used by mid-strata-consumers, sometimes even low-strata-consumers as they were generally situated outside the happy-zones. In turn these 'hangars' were developing into a quasi-outlaw areas.
Abysmal maintenance and repairs due to failing happy-points-situations turned these areas into more and more derelict zones, which had to be frequently raided by Happy-Security in order to keep a minimum level of law and order.
