The Known World
A world in the early years of its growth. boarders still being drawn in some regions, lands being claimed in others and tales being forged everywhere.
Yr. 340 is the oldest I have built in. I'm still in the early stages of the world and will be fleshing it out with the gaming table I DM.
The use of the Upton Guild has helped not only with the building of the world but also with plague all us DM's have of missing players on game day.
it acts as a one shot adventure catalyst.
