Depends how you want to roleplay it. As you'll see from http://www.uesp.net/wiki/Morrowind:Marandus, all the people in and around Marandus are Redorans. The ones outside have lower Fight values, which is why they don't attack you (if your Redoran faction reputation is high enough, the ones inside will leave you alone as well). Exactly why they're occupying an abandoned Dunmer stronghold, far from Redoran territory, is unclear.
If you're sympathetic to Redoran, you might want to leave them alone (or get the LGNPC Pax Redoran mod, which allows you to make friends with them). Otherwise, I guess it's up to you if you want to kill them (they do attack first, after all) and loot everything that isn't nailed down.
