Item #: SCP-023
Object Class: Euclid
Laconic Containment Procedures: SCP-023 must remain in a walled-off intersection of corridors fitted with three fake doors and four real ones. SCP-023's eyes always have rubber inserts covering them. They must be replaced due to degradation, but only individually and after the sun has set. No one should look directly into SCP-023's eyes, and no reflective surfaces should be in the enclosure. Testing on SCP-023 currently remains suspended.
Laconic Description: SCP-023 is a large, black dog capable of passing through walls when not kept at a crossroads. Anyone who makes eye contact with SCP-023 will die or have a close relative die within one year. Anything killed in this manner will slowly become filled with ash after death.
Additional Context: This SCP likely got inspired by the barguest or 'black dog,' a creature in British folklore said to cause bad luck to befall anything that saw it.
