Plagued Skies

This mod creates an effect where the sky slowly grows over with plague blocks, which slowly block out the sun, until the dragon's egg is returned to the overworld to break the curse.

Curse blocks will randomly spawn in the sky near online players, and will slowly spread (similar to how grass spreads over dirt). Several aspects of this spread can be configured via config file.

This is intended as a support mod for the upcoming "Creeping Dark" mod pack.
