 SCP-518 is a localized anomalous phenomenon, catalyzed by the dissemination and exposure of SCP-518-1. SCP-518-1 is a short narrative, first documented upon the initial exploration of SCP-518. Whenever SCP-518-1 is read in its entirety by a sapient, comprehending individual, SCP-518 undergoes spontaneous physical changes. In most cases, these changes entail the movement of structures in relation to each other, rearrangement of the interior features of these structures. In some cases, readings of SCP-518-1 will cause new structures to appear, or existing structures to simply cease to exist.
