I would consider this a low tech campaign;
- Cultural centers are not prosper enough to be conducive to ‘research’.
- An item like a cross bow would be to expensive to widely implement a crossed the entire Marshallet for example.
- Do to the low Magic of the game unless very old there are few unique or fantastic items.
I think creates a time and space early in this world for the players to be the ones who produce the great items that ages from now other adventures will seek.
