Olympia: The Age of Gods PBEM (Oct 4 2000)
When a player quits, all his nobles die, except those that are being held prisoner by another nation. Those nobles become "refugees" and can be converted at no NP cost by anyone.
Most of the goods being held by the nobles who die are lost. Unique items (such as artifacts) will typically fall into the location where the noble dies, and can be found with explore.
