INDEX Analysis
The Exit Portal is a dense colony of Sprawl contained and monitored aboard the Pioneer. Formed when samples of fossilized Chimera DNA from the Tunguska meteorite revived and evolved. (INSERT: Mira - That was... surprising.)
REACT R&D have limited the Portal's evolution using pulsed magnetic field generators. The fluctuating containment field is monitored by INDEX.
The Exit Portal is linked to Singularities found in the field. First confirmed by the reappearance of Operators Alibi, Sledge, and Vigil after three weeks MIA inside a Singularity.
ADDENDUM: Operator reported being out of contact with REACT for 15 minutes. Post-incursion medical assessment showed advanced cellular senescence. Treated successfully.
EXTRAPOLATIONS:
Theorizing on formation of Portal: Studies conducted on fossilized Chimera DNA may have caused it to reawaken. Radiological, spectroscopic, and chemical triggers have been ruled out. Study ongoing.
Quentum entagement between the Portal and the Singularities is being studied. (INSERT: Mira - If we could learn to control this thing. To USE it. Who knows where it could lead us.)
PROTOCOLS:
Operators returning through the Portal must undergo immediate medical and psychological assessment.
