Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: Due to SCP-XXXX's immobile nature, a concrete bunker has been constructed around it for containment. Two guards are to be observing SCP-XXXX at any given time, and a Mobile Task Force remains on site to respond in the event of a breach. No personnel are to come within ten meters of SCP-XXXX at any given time.

Any instances of SCP-XXXX-1 that emerge from SCP-XXXX are to be sedated then contained. If attempted containment proves too great a threat, then use of lethal force against SCP-XXXX-1 instances is authorized.

Description: SCP-XXXX is a 6-meter high, 6-meter wide, 10-centimeter thick oval-shaped structure comprised of quartz crystal. SCP-XXXX hovers 10 centimeters above the ground at all times.

SCP-XXXX is currently immovable. Any lifeform that makes contact with SCP-XXXX begins to undergo transformation into a tar-like substance. With complete transformation taking between 20-30 minutes. No outward symptoms are evident within the first minute of transformation, though change does occur on the cellular level. A tar-like appearance becomes evident within 5 minutes, and complete transformation invariably occurs within 30 minutes. Solid non-living material will also undergo a similar transformation within a 10-20 minute time span.

SCP-XXXX has two states active and inactive. When inactive SCP-XXXX shows no anomalous properties apart from hovering and the effect that occurs when touched. When active a currently unidentified blue glowing substance fills the entire area inside SCP-XXXX.

After one minute the substance disappears and the area inside of SCP-XXXX shows an alternate reality. If a subject can pass through SCP-XXXX without touching its frame they will find themselves inside said alternate reality.

So far most areas inside SCP-XXXX have been cities or towns in ruins. However, other areas have been recorded:
-A desert
-A rainforest
-A forest
-A tundra
-A school
-An asylum
-A museum

If a subject spends 30 minutes inside SCP-XXXX then an instance of SCP-XXXX-1 will materialize and begin to pursue the subject until the subject is terminated or incapacitated. In most cases, SCP-XXXX-1 instances seem to prefer to keep a subject alive.

Once the subject is terminated/incapacitated SCP-XXXX will re-enter its inactive state. If SCP-XXXX is left in its active state with no interference SCP-XXXX will enter its inactive state after 10 hours. SCP-XXXX will stay inactive for 15 hours then re-activate for another 10 hours.

Any lifeform that comes within ten meters of SCP-XXXX when in an active state and keeps this distance for a minimum of eight minutes then an instance of SCP-XXXX-1 will materialize and emerge from SCP-XXXX.

Recorded forms that SCP-XXXX-1 instances have taken since 2001:

-A bipedal dimetrodon.
-A 10-meter long Pythonidae snake comprised of with a frill on its neck that could expand by 10 centimeters.
-A Latrodectus hasselti (redback spider) 50 times bigger than normal.
-A black Lumbricina (earthworm) 15 meters in length and similar in thickness to a Eunectes murinus (anaconda).
-A canine the size of the average Equus caballus (horse).
All SCP-XXXX-1 instances are comprised of tar.

Addendum XXXX 1:

Test A - Date: 2000

Item: SCP-XXXX
Procedure: D-3192 entered SCP-XXXX armed with an incendiary charge and had a camera mounted on his helmet.
Results: D-3192 arrived next to a hut in the middle of a desert. D-3192 entered the hut and located a message written in tar reading "Iawhmree?" D-3192 walked into a basement and located a cave. A screech came from the cave and D-3192 ran out of the basement. D-3192 spent 30 minutes inside SCP-XXXX and an instance of SCP-XXXX-1 materialized. D-3192 pulled out the incendiary charge, attached it to the SCP-XXXX-1 instance. D-3192 ran from SCP-XXXX-1 before activating the charge. D-3192 found a book in the sand labeled "Iemarrofini". D-3192 returned with the book.
Analysis: It seems instances of SCP-XXXX-1 have a "nest" and are capable of writing. The recovered book has been given to Dr. ███ for analysis.

Addendum XXXX 2:

Test XXXX B - Date: 19██

Item: SCP-XXXX
Procedure: D-████ was told to stand within 6 meters of SCP-XXXX for 15 minutes.
Results: An instance of SCP-XXXX-1 (taking the form of a humanoid figure) emerged from SCP-XXXX and grabbed D-████. The SCP-XXXX-1 instance threw the subject through SCP-XXXX, the instance then attempted to grab SCP-XXXX but it "hands" passed through it. The SCP-XXXX-1 instance was successfully sedated and put into a containment cell.
Analysis: It appears that any entity created by SCP-XXXX will not be able to touch it and pass through SCP-XXXX's frame.

Addendum XXXX 3: SCP-XXXX is undergoing safe classification after instances of SCP-XXXX-1 no longer emerge from SCP-XXXX.
