The containment chamber was the first thing the Institute built. Ilse Varga had it poured around the rift before anything else: concrete three metres thick, with one door that opened only from the anteroom, and two guards in the anteroom at all hours (T-001). The first rule was painted on its door: no one entered the rift, touched it or put any object into it without the written order of the Director (T-001).
Everything that came through in the first years came out here. The first stalker crossed the dark of the anteroom on the hundred and seventh night (T-002), and the response team fought the first brute in the anteroom for eleven minutes (T-003). The chamber was inspected every week, and in year 7 the inspection found the growth spreading over its floor from the foot of the rift. It was burnt back from then on and always came back (T-006). The old records room off the anteroom was the room that turned upside down (T-014).
From year 24 the surveys went through the rift from the chamber (T-017). In year 48 the widening carried the rift past the chamber's walls on its third day, and containment failed on all levels (T-055).
