Skymall is a shopping facility built February 23, 2016 by Mapcratic and Junglemason. It is located on Marosticalia continent at 48309, -2415 along Intersnout 10. It was built in part because of the problems with Mako Mall including a broken chunk. It was designed to provide "microbuild" type store footprints to facilitate quick visits of multiple stores. Redstone circuits, armor stands, and item frames are banned here to prevent lag problems.
A prototype mall can be found just north of East City (/res tp east) at 60620,850. This is near world's edge in the supporter region.
