Southern Exclusion Zone

The Southern Exclusion Zone (SEZ) was a large and extremely hazardous area that bordered Great Britain, the Thames Republic and the Republic of Wales. It intersected the historical counties of Hertfordshire and Essex, and was declared to be a no man's land. The area was created during the London Revolution, when retreating Helios Private Military Corps forces detonated a number of Entropic Flashover Bombs (EFBs), severely corrupting its manifolds. The manifold damage in the SEZ led to the attenuation and shifting of high frequencies, resulting in disruption of radio transmissions and the alteration of sunlight, leading to the zone exhibiting a distinctive red sky.

Thanks to the advent of groundbreaking research and monumental cleanup work performed by the Department for Exophysics, patches of the SEZ are no longer uninhabitable, allowing some of its original occupants to return, and entropic radiation levels in the area are eventually expected to return to normal. Key rail routes have also been re-established through the zone.
