Sadr Region

The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is the diffuse emission nebula surrounding Sadr (γ Cygni) at the center of Cygnus's cross. The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae.

gollark: Anyway, the most promising approach for sort of bodging a future-reminder system is either just guessing likely messages (probably won't work, people aren't that predictable if they're saying more than just "no" or "yes", though I guess any message in <#481655540976451584> is fairly likely to be said again), or trying to force people to conform to the predictions.
