Report: Incident GAMMA/DELTA-A

Foreword: SCP-GAMMA, along with two D Class personnel, had almost finished performing SCP-3590, after 27 minutes elapsed since the start of the ceremony. D27-382 and D27-876 had successfully performed SCP-3590 along with SCP-GAMMA ██ times before the incident. Research team assigned to SCP-GAMMA at the time oversees the procedure via CCTV. Events transpire inside the now decommissioned IRBE27/GAMMA containment cell.

<Begin Log>

<16:18> D27-382 blows the fifth candle, thus finishing his role in SCP-3590.

<16:19> D27-876 approaches SCP-GAMMA, placing the third crucifix around its neck.

<16:19> Last chants are sung in unison by D27-876 and SCP-GAMMA.

<16:20> SCP-3590 concluded. Research team confirms recession on the Scranton scale. SCP-GAMMA seem relieved and proceeds to thank D27-876 and D27-382, whom it addresses by name. Behavior in line with previous observation.

<16:22> D27-876 and D27-382 finish collecting materials used in SCP-3590, as instructed by Research team. No consumables left.

<16:23> D27-876, D27-382 and SCP-GAMMA make casual conversation while exit quarantine protocols are lifted.

<16:25> Confirmed malfunction of IRBE27/GAMMA's entrance. Tech team dispatched to access the problem. D27-876 and D27-382 instructed to await their arrival.

<16:28> Sharp increase on the Scranton scale. Source unknown, presumably SCP-GAMMA, though the entity continues to converse with D Class personnel. No visible changes inside containment cell.

<16:28> Quarantine protocols automatically reestablished. Tech team ordered to await further instructions. D27-876, D27-382 and SCP-GAMMA seem confused over the development and are told to remain calm while the Research team deals with what appears to be an equipment failure.

<16:30> State-wide warning regarding SCP-DELTA breach of containment issued by Site-29.

<16:31 to 16:35> Steady increase on the Scranton scale is matched by elevation of radiation exposure detected in D27-876's and D27-382's implants. Readings of approximately 40 mSv confirmed.

<16:36> North and south walls of the containment cell undergo severe warping, incompatible with that which a Class I Reality Bending entity should be able to induce given the cell's [REDACTED]. D27-876, D27-382 and SCP-GAMMA are visibly distressed and attempt to escape through containment door, which remains inoperable.

<16:37 to 16:38> Formation of a Hartle IV class space-time anomaly inside IRBE27/GAMMA confirmed. Anomaly expands until both its axes measure roughly 1 m.

<16:38> SCP-GAMMA coerces D27-876 and D27-382 to perform SCP-3590 again. D Class personnel complies, despite being ordered otherwise by Research team.

<16:39> SCP-DELTA begins to emerge through the Hartle IV class anomaly, as four of its appendages become visible in video feedback. SCP-GAMMA is now panicking while it further attempts to coordinate with the equally distressed D Class personnel in order to perform a second rendition of SCP-3590.

<16:40> First instance of SCP-DELTA-B, ''Laughter'', is emitted by SCP-DELTA as its head passes through newly-formed space-time anomaly. As well documented, all sounds produced by SCP-DELTA, namely SCP-DELTA-A through SCP-DELTA-E, are considered auditory cognitohazards and receive individual designations. Research team suffers no adverse effects due to previous inoculation; attempt to perform SCP-3590 interrupted, as D27-876 and D27-382 are effected by SCP-DELTA-B and promptly [REDACTED]. SCP-GAMMA is unaffected, but increasingly desperate.

<16:42> Request to rescue SCP-GAMMA denied by Site-27 administration on grounds of possible escalation of SCP-DELTA containment breach. SCP-DELTA has now fully emerged though Hartle IV anomaly and continues to emit SCP-DELTA-B at regular intervals. Space-time anomaly remains stable. SCP-GAMMA begs to be released from containment while addressing one of the cell's cameras. Footage review reveals SCP-GAMMA seemingly struggles to vocalize, possibly documenting the first instance of the anomaly associated with SCP-3590.

<16:43> SCP-DELTA attacks SCP-GAMMA, while it continues to emit SCP-DELTA-B.

<16:45> Research team requests immediate deployment of SRAs to aid in re-containment of SCP-DELTA and prevent the expiration of SCP-GAMMA. Denied by Site-27 administration on grounds of [REDACTED]. Standard Class III Reality Bending containment protocols enacted instead.

<19:05> SCP-DELTA stops emitting SCP-DELTA-B and remains inert after scattering the last remains of SCP-GAMMA throughout the cell. After a few attempts to breach the containment door, SCP-DELTA retreats through the Hartle IV anomaly, which remained stable during the incident.

<19:06> Hartle IV anomaly recedes.

<19:08> Site-29 confirms reestablishment of SCP-DELTA containment.

<19:08 to 20:31> Screams in what resembles SCP-GAMMA's voice continue to be heard through monitoring system, though no source is identifiable.

<20:32> No anomaly detected inside IRBE27/GAMMA. Quarantine protocols lifted. Recovery teams dispatched to collect relevant materials. IRBE27/GAMMA decommissioned according to previously enacted protocol.

<End Log>

Closing Statement: Personnel assigned to SCP-DELTA containment at Site-29 reports the appearance of a Hartle IV space-time anomaly inside SCP-DELTA's containment cell similar to the one described in this report during its breach on ██/██/████ - it is inferred that both anomalies were, thus, connected and facilitated said containment breach, along with the further development of Incident GAMMA/DELTA-A. How these anomalies were formed is not currently known, but studies are underway.
