A Traveller setting.
A hundred years after the Third Imperium tore itself apart in civil war the major powers are beginning to rebuild but are less powerful than they once were and pocket empires have proliferated.
This setting continues on from that of Traveller:The New Era but can be used with any version of Traveller rule set.
We are grouping the original "New Era" (set in the first few year 1200's) and "New Era 1248" material ogether as a single setting. While separated by a few decades so there are some changes described between the books they cover the same area while it still has the same basic type of world without major changes, we don't have a new setting just because the next source book advances a year or two, and in this case we don't think even a few decades makes it a new setting.
