This Sector is home to the Holster Cells where the various human-tested experiments, or subjects are kept. They are kept incredibly hidden, and only the Internal Security Department Agents, higher ranking Research Divisional Members, or the Rapid Response Teams are allowed here. Internal Security and Rapid Response armouries are kept here, as well as the higher ranking Site Alpha Command Offices. Any personnel from Alpha attempting to even enter Heliosis’s airlock must gain permission from all on-duty Site Alpha Security Corp members. This Sector is heavily guarded at all times, due to being one of the last Site Alpha Sectors, and right near the Dark Matter Reactor and Orbital Cannon. The Cellblocks within this Sector are separated into four different parts, each with a supposed different purpose. Cellblock A, B, C, and D all respectively.
