Star Realm

The Star Realm is an area briefly mentioned in Mario and Luigi: Partners in Time. It is talked of by the gate in the Star Shrine when he commands you to get the Aurora Block, something which is apparently very sought after by the denizens of this mysterious place.

The Star Realm most likely includes the Star Shrine, and may or may not include Star Hill. Other star-themed areas not seen in Mario and Luigi: Partners in Time (such as the Star World and Star Road) could also make up the Star Realm, or it might be an individual area in itself.

Not much is known about this obscure place.
