It is currently impossible to contain The Entity, for it is capable of phasing through walls. When some information regarding SCP-2521 was downloaded into the machine 2521 attempted to claim 68 absorbed 2521 causing the machine to change and augment itself while 6820 gained the ability to manipulate its own documents. The destroyed idea and its avatar 682, which because of SCP-6820 was now forgotten by everyone and designated SCP-6820-A, infected the machine which caused the Foundation to find a way to destroy it at any cost and tried to use several SCPs to destroy the machine, which also included SCP-2521. In an alternate universe in which the Foundation killed SCP-682 by using SCP-6820 to destroy the idea inhabiting an alien noosphere that manifested in the form of 682. At its final moments, SCP-2521 was possibly approached by SCP-4999 and both of them seemingly died together. When the event only known as SCP-6500 began occurring, SCP-2521 was one the many anomalies being neutralized by it. This caused the effects of both SCPs to be nullified, as following their cross-test SCP-INTEGER shared its identity with 2521 causing the latter to start relentlessly chasing it down. Possible Endings SCP-001 (Ihp/Locke Proposal)Д«ecause of Site-100's manipulation, SCP-2521's name was simplified to NARCISSIST by SCP-INTEGER. The creature is presumed to be 2521 given that the D-Class couldn't describe it, since it would be taken away, meaning that SCP-1346 was the prison of 2521. The D-Class, however, refused to describe the creature in the letter, because it would be taken away, and wished luck to the Foundation in containing it. In the letter he wrote how the room he had entered was actually a prison which contained a creature, and when he entered he accidentally took its place, freeing the creature who then left. However, the D-Class never got out, but was still alive as he had slipped under the door a letter for the Foundation to find. This experiment somewhat worked as the D-Class didn't develop fear until he arrived to the door where he finally developed fear and nearly collapsed however, the shock collar he wore caused him to reawaken and, for the first time, someone entered through the door. This effect will eventually cause subjects to refuse to proceed further and go back when exiting the corridor, this fear will go away and the subjects will be confused as to why they were scared in the first place (though subjects retained the trauma in some cases).Д®ventually, after some failed experiments, the Foundation sent a D-Class who had SCP-3031, a rare brain condition, which caused him to not develop fear. As subjects keep going, they will begin to experience intense fear as they go near the door. When subjects start to go to the end of the corridor, their electronic devices will cease to work and subjects will begin to hear clicking and other mechanical sounds despite some subjects using items to prevent hearing. SCP-1346 as said, is a corridor in the basement of an unknown engineering company building that at first seems normal, with the exception that the end of the corridor where the door designated SCP-1346-1 is, is dark and in disrepair due to its anomalous effect. It's possible that SCP-2521 may come from SCP-1346-1, a room behind a normal looking door in the end of corridor which is designated SCP-1346. It is not evil, but just wants to know about itself, that's why it steals documents and people who described it, in order to find more information about itself. Its own origin is a mystery even to itself, not knowing what it is, what its real name is or where it came from, which saddens the creature. In the tale 'Please Say My Name', SCP-2521 is depicted as sympathetic. SCP-2521 is a large creature, standing almost twice the height of a normal human, its entire body covered in layers of sticky black tendrils akin to ribbons, although it is unknown if it is made of these or is simply covered in them.
