The Planets' spawn point.
The Planets is the central hub, created in 1.6.2 on August 17, 2013. It is named after a song by Ludovico Einaudi. It is based in The End, and each world has a separate portal (an exit End Portal) leading to either its spawn point or another major destination within that world.
