Is there any way to get a permanent settled population on Mauritius and Reunion before Europeans? Could they be settled by Austronesians at around the same time as Madagascar, from Indonesia or from refugees from Madagascar pushed out by migration? Or would it be a better bet to wait until later for colonization by Arabs or Indians (and what would motivate that colonization?)? What would any of these societies look like, and how would they interact with the world? What would European colonization of this island society look like, if it occurs?
