Time Travel (Appalachia)

I seem to be building three campaigns within the Appalachia setting.

1. Hispaniola starting in 1512, focused on present day Latin America, pirates and conquistadors and having the high elves driving all the Iberian settlers back to Hispaniola.
2. The human invasion starting in 1612.
3. The Indian elven reconquest starting in 1712.
4. Appalachia proper starting in 1812.
5. Pacific starting in 1912, focused on the areas surrounding the Pacific ocean.
