what is SCP-4130?

That’s part of why I haven’t written anything about it, but it would definitely be a Homestuck Reference. Maybe it’s Scratch’s Cue Ball, or it could be the Green Sun and radiation proceeding from it… Actually you know what, that could be a fun idea like. An Euclid Class radiation signature proceeding from beyond the boundary of the observable Universe, but detectable, unique, and seemingly manifesting through a canine-like entity warping through the Earth but mainly localized within an isolated, uncharted island in the middle of the Pacific Ocean.
