Death in Starmourn will work like this:
All players have an internal neural replicator (INR) that is continuously updating itself with a full model of your current brain activity.
Players will all also have a sample of your DNA at a cloning facility, which are all run by the Atarsid organization called the Hon-En-Tur Exaltation, who turned to cloning to replenish their devastated species after the Third Cleax Invasion, and are the foremost experts in cloning now. Players select a particular cloning facility to be their default one, and can change it whenever they wish.
When a player dies, they'll be resurrected at a cloning facility minus a small bit of their xp. If they feel like it's worth it and they died in a way that saw their INR survive, they could go back to where they died, retrieve their INR, and get a good portion of that xp back.
However, anyone can retrieve that INR, and if they choose to use it on themselves, they’ll get a portion of that xp for themselves, though less than you’d get back if you used it yourself. Or, they could choose to sell it back to the player that died, or to someone else. That’s a nasty thing to do, of course, but Starmourn’s full of space villains (some of them are probably reading this now).
