A possible idea for a setting has occured to me, based on the default Iron Heroes (a variant D&D 3rd Edition setting and ruleset) setting.
"Once, the world was ruled by mighty Mage-Lords. These godlike and near-immortal beings may or may not have been human, but their powers were almost limitless. They built great cities, summoned servant races from other realms or spawned them in their laboratories, made many powerful magical artifacts, ruled an empire that spanned worlds... And finally, for whatever inscrutable reasons, turned on each other in a war that lasted for generations and left the world a blasted ruin, with the Mage-Lords themselves dead or otherwise vanished.
It is from the ashes of this was that the present day is struggling to rise. Here and there, amidst the ruins of the glorious bygone age, handfuls of people are beginning to rebuild. Groups of vagabonds come together and try to make small islands of security and prosperity amidst the devastation. Intrepid bands of adventurers venture into the ruins, braving the warped and uncontrolled beasts to recover the treasures of bygone days. And a handful of scholars study the few fragments of the Arcane Arts that remain and dream of reclaming the power the Mage-Lords once wielded."
This setting has several advantages.
Firstly, it can use the standard D&D toolset, meaning no waiting for new models or having to make our own.
Secondly, it means we can design the world by increments and not have to worry about anything outside our current area of play. We simply build the initial settlement, then add bits as we go and assume people are slowly exploring outwards. There is no need to think of large countries which we can only see small parts of- what we see is what we have.
Thirdly, it gives a focus for the group as a whole inherent to the setting, which is equally suited to combat and RP. The standard D&D experience system gives XP for combat, so I assume that NWN2 has the same, which means combat wouldf have to come in at some point.
Finally, the fact that Magic is a "lost" art means that there can be a limit on the power of magic using characters placed on the setting, which is something that several people have expressed a preference for.
Opinions?
