Hussar said:Well, our own world remained PoL (at least Europe anyway) for about 1000 years (500 AD to 1500 AD) and numerous other parts of the world for MUCH much longer than that. Heck, North America and Central America were PoL almost to the present day. Certainly within our own grandparents lifetimes.
1000 years is more than enough time methinks for most campaign worlds to tell most of their stories.
The idea that high level PC's will become permanent fixtures in the world is actually not supported. For one, elves had their lifespans chopped significantly. 3e lacks life extension magic a point that was used to great effect in Scarred Lands.
Actually SL sounds a LOT like a PoL setting. Small city states surrounded by extremely dangerous countryside. Life within those citystates is fairly good, but outside of those "points of light", life is very nasty, brutish and short.
Heck, thinking about it longer, there's large amounts of world history that looks an AWFUL lot like this.
For 1000 years we had no power (read technology). As soon as we developed it, PoL was over. D&D inhabitants have more power (read magic) than we do.
