Monoliths

Monoliths are items introduced in the 1.3 update. They have no power at all, but merely change the background as if you were in the lunar event. they cost 15 of whatever type of fragment you want. ex: lets say you want the solar flare background in your world. you take 15 solar fragments to the ancient manipulator and you get a solar flare monolith. place it down and your background will change to that of the solar flare portion of the lunar event
