Object Class - Thaumiel

SCP-5674 is a small blue light at the edge of our Galaxy. Not much is known about this SCP as it is only visible for a few seconds every five years.

When observed it seems to be forming a circle around our Galaxy. It is unknown if this is a sentient being or just an asteroid stuck in an orbit but what is known is that the circle it makes seems to stop SCP-5673 from entering our Galaxy.

Known currently as “The Arc Barrier” SCP-5674 is one that is currently preventing an extinction level event.

This SCP has only recently been discovered by Dr Lee. Dr Lee observed an incident with SCP-5673 and saw SCP-5674 move past it stopping it in its movement.
