Soul Storage

Soul Storage is a structure that spawns in the Underworld when the Moon Lord is defeated. When it appears the message "The depths of the world begin to change" appears. The structure is square in shape and made out of Demonite/Crimtane bricks with Demon Torches as lighting. In the center is a sphere filled with numerous red clouds that can be broken with a hammer that has a hammer power of 100. When the sphere is broken the message "The souls of your foes want a rematch" appears and one minute after that the Boss Rush event will occur.
