Star Road (Super Mario RPG)
In Super Mario RPG: Legend of the Seven Stars, Star Road plays an integral role in the plot as the place where all wishes are turned into Wish Stars before being granted upon collision with the world. During Smithy's journey to Bowser's Keep, his ship Exor crashed into Star Road, shattering it into seven Star Pieces. As wishes could not be granted until the road was repaired, a person identified only as "a higher authority" sent the star warrior Geno to collect the Star Pieces, thus repairing the road. In the end, Geno was able to fulfill his duty and Star Road was presumably left in order, although it did appear to be covered in stitches after the accident. When it is seen in Super Mario RPG's ending, the Star Road looks immensely similar to Super Mario World's Star World, being a giant, floating star found high above clouds in a screen featuring the Moon to the upper-left.
In Paper Mario, the aspect of wish-granting in Mario's universe would be seen in further detail. Star Haven is a Star-inhabited place out in space where Star Kids are raised to grant a person's wishes. The Star Spirits also form a council and use the Star Rod to determine which wishes get granted. Star Hill also makes its first reappearance (renamed "Shooting Star Summit" in the English version, possibly due to renewed copyrights), given a slightly different role but still a place where the stars fall.
