Improve your Grammar please. Here's what would sound nicer:
These 4 floating isles, often called Satanica could be the doom of it's settlers. Settle with 3 other players and defeat them. But beware, Satan never sleeps!
Sorry but I don't like the idea of using the same noun or adjective, as in your case: settle and settlement, in the same sentence.
I haven't downloaded the map but I'll check it out (Bandit!) when I have the time.
Looks pretty good, and I like the idea so far.
