SCP-575
Description: SCP-575 appears to be an unknown form of matter, taking the form of a series of amorphous black shapes and structures. SCP-575 is difficult to observe, as it immediately dissipates when exposed to light1. Current testing has been unable to identify if SCP-575 is organic or inorganic. Despite the lack of any visible nervous systems or observable organic components, SCP-575 displays behavior consistent with an active consciousness.
