Something went terribly wrong when Sombra was banished to the Sun as punishment for escaping the curse in the Frozen North and being a constant thorn in Equestria's side.

Cadence couldn't even figure the spell out, Twilight and Luna said it was too far away for them to reach, and Celestia said something was blocking her grasp of it.

Nopony could pull the Sun closer and whatever happened changed Equestria rapidly. Then came what everyone called Sombra's Final Curse.

Inspired by Hinterland's The Long Dark (not a fic/story otherwise on the site, not MLP:FiM related. As a result, some things may seem unrealistic) and as a love letter to my favorite season.
