The blue moon of Sancstoryl, associated with the goddess Selûne. Salu is actually a fairly popular spelljamming port, with even a handful of Sancstorylian trade ports on its surface. For many people, Salu is the trading epicenter of Sanctospace. If you need something, from magic items to spelljamming vessels and devices for plane shifting, you can most likely find it on Salu. For the people of Sancstoryl, Salu is also the only way to get their hands on a spelljammer for themselves, due to ancient laws that only allow the trading of spelljamming vessels on Salu. However, this monopoly seems to be slowly crumbling, as Sancstoryl has entered a new age of innovation. It's mostly inhabited by Moon Elves, as well as quite a few wildspacers of varying races.
