Red Raven Signals

Red Raven Signals, commonly known as RR Signals, are a type of radiation originating from the Other Side.

Overview

RR Signals are native to Other Side, they seem to generated by shadows of the people trapped in Other Side, with shadows of the S.M.V victims generating the strongest signals, and by the Red Things.

Devices such as OsRat and radios of the Deekula B3 bathroom are capable of detecting RR Signals leaking into the real world, and by extension, establishing a connection with Other Side, without using Green Mushrooms.

Usage of Polonium-210 in OsRat may suggest it is the key component of being able to detect and interact with RR Signals in real world.

Name

In INFRA, one of sites listed by S.N.W, a cave where the Green Mushrooms were found for the first time, is designated a "RR", possibly also meaning "Red Raven", and having a relevance to the signals.

In Obenseuer, Wizard Welhö tends to call out "By the Red Raven!" in anger or disbelief, suggesting the name has further meaning besides just being a term for signal type, and that it may have a blasphemous meaning.
