Object Class: Euclid

Special Containment Procedures: SCP-X is currently housed within an enclosure measuring 5 km in diameter surrounded by a twelve (12) ft. cement wall beginning four (4) ft. below ground. The wall is to be topped with barbed wire which should be inspected each week to ensure it is still in place. Surveillance cameras are positioned atop the wall to provide views of the inside and outside of the enclosure at all times. Wireless underground motion sensors are placed every five-hundred (500) meters within the enclosure and every fifty (50) meters around its perimeter. Any motion sensor activity is to be immediately reported to Doctor Baker. Personnel are not to enter the SCP-X enclosure without orders from Doctor Baker and confirmation of those orders from at least one other site researcher.

Description: SCP-X is the designation given to a collection of forty-seven (47) trees found growing in the Black Rock Desert region of Nevada, USA. SCP-X instances have three known life stages, designated SCP-X-1, SCP-X-2, and SCP-X-3.

Instances in the SCP-X-1 stage have highly malleable black bark that is dry to the touch. These instances have small white leaves and employ CAM1 photosynthesis. Instances in the SCP-X-1 stage experience no seasonal change of colour in their leaves. In order to move on to the SCP-X-2 stage, SCP-X instances must ensnare a human body, an action which they carry out by the opening of the bark and the extension of up to six dark green vines, four of which are used to overpower the human subject, whilst the other two are used to burrow into the subjects skull and spinal cord. Once these vines have reached the subarachnoid space they begin to drain the cerebrospinal fluid from in and around the brain and spinal cord, with complete drainage taking up to 20 seconds. The destination of this fluid after drainage is unknown. Once the fluid has been completely drained it is replaced by a dark green fluid which is pumped into the subarachnoid space through the vines. The subject is then either pulled inside of the SCP-X instance or is seemingly rejected and left on the ground as the vines retract and the bark closes. Rejected subjects have survived, but remain catatonic indefinitely. If the subject is pulled inside the SCP-X instance, the bark will close and the SCP-X instance will progress onto the SCP-X-2 stage.

Instances in the SCP-X-2 stage develop a dark red bark that is sticky to the touch. These instances have large dark green leaves which turn a bright red in the winter months, and also employ CAM photosynthesis. Human subjects within instances at this stage are coated in a translucent ooze which, besides eroding away all items of clothing, appears to function as a method of supplying vitamin D to the subjects. The two vines that are initially placed inside the brain and spinal cord remain, whilst the other four vines are placed into various areas of the body, apparently for maintenance purposes. The first attaches itself to the aorta through the subjects left side, the second attaches itself to the inferior vena cava through the right side, the third attaches itself to the bladder through the urethra, and the fourth attaches itself to the colon through the anus. Although subjects experience muscle atrophy due to lack of movement, they appear to be healthy as long as they remain connected to the SCP-X instance. Subjects experience high levels of brain activity, especially in the amygdalae and hippocampus, as well as high levels of rapid eye movement.

If a human subject is removed then the SCP-X instance will enter the SCP-X-3 stage at which point the instance will shed its leaves and its bark will become brittle and grey. Photosynthesis ceases entirely in this stage. So far no instance has reached this stage without outside influence, and no instance has recovered after entering this stage.

Of the forty-seven SCP-X instances, twenty-one are currently in the SCP-X-1 stage with twenty-four in the SCP-X-2 stage, and two in the SCP-X-3 stage. Of the twenty-four subjects housed within SCP-X instances, two are foundation personnel, one being a member of the taskforce that initially identified the anomalous properties of SCP-X, the other being a D-class. In total, five foundation members have succumbed to SCP-X instances, three being implanted (One of which was later removed to investigate the short term effects of implantation.) and two being rejected.

Addendum 1: After security feeds on the perimeter of the SCP-X enclosure where observed to have spontaneously failed, security personnel were dispatched to investigate. Upon arriving at the enclosure, personnel found that the perimeter fence2 had been seemingly pulled into the ground, leading to the destruction of the mounted surveillance cameras. In light of this, Dr. Baker ordered for an excavation of the SCP-X outer root system, which revealed massive expansion as far as 5 km outside of the enclosure in some areas. Authorisation has been given to remove significant portions of the root system via any means necessary.

Addendum 2: SCP-X has identified itself as a sentient entity. Whilst work was being carried out to dismantle the expanded SCP-X root system, present personnel were greeted by an occupant of an SCP-X instance, who was extended to the edge of the enclosure via vines wrapped around its arms and legs from two unoccupied SCP-X instances. The individual identified itself as SCP-X and requested the presence of Doctor Baker by name.

Addendum 3: Following O5 approval, the SCP-X enclosure is to be extended to a 2.5 km radius to accommodate the expanded root system. Any further growth within the enclosure is to be reported to Doctor Baker immediately.
