We're considering adding a small number of sky islands for rent in the Lunamere region. Because this region is designed for sailing, we can't create mid-region parcels with their own settings (parcel boundaries, media/music, access lists, privacy, etc.) without disrupting the experience.
Sky islands would be floating build spaces placed 100-300m above the water. We’d do the initial placement/light landscaping for cohesion, and you’d have most of the island to decorate within covenant guidelines (no airships, sorry).
You wouldn’t be able to change parcel settings, but you could use a security orb to protect your space, and there would be a prim counter to help you stay within your LI allotment. This would mean that other avatars would be able to see you, should they cam in on you.
