SCP-2639 refers to a phenomenon that manifest as a 1 kilometer cube volume wherein anomalous entities and objects(designed SCP-2639-A and SCP-2639-B, respectively) materialise, then dematerialise approximately 1-2 hours later. An imperceptible barrier around SCP-2639 prevents instances of SCP-2639-A from leaving this area of effort. SCP-2639-A are 3 humanoid entities equipped with anomalous weaponry and armor. Each entity exhibits superhuman speed, strength, endurance, resistance to injury, and perceives no pain to discomfort. When an instance is destroyed, an undamaged copy of this instance will appear somewhere within SCP-2639 area of effect. SCP-2639-B consists of 22 distinct types of intangible objects dispersed throughout SCP-2639 area of effect. Each instance hover 0.1 meters above ground and rotates on a horizontal axis at a set rate. When instances of SCP-2639-A make contact with an instance of SCP-2639-B, the object will typically vanish conferring a beneficial effect on the entity. Observed effects have included(but not limited to) new anomalous weaponry, increased resistance to injury and higher overall damaged input.
