Help Designing a colinization game-

[Vagabond?]

So, I have a game working where the party is composed solely of Wizards, and they have to go colonize a colony in another dimension, but I'm not entirely certain what will actually lie in that dimension, nor how to design that game.

As it is, I'm not sure what to have as the BBEG, or whether to have a BBEG at all, or whether to simply make it so that nature simply is trying to kill everyone, or what.

When you say colonize, do you mean, like how European nations colonized and made deals with various indiginous peoples? Like Christopher Columbus and the Native Americans?

Or do you envision just making a new Kingdom out of unoccupied territory in another plane?

For the latter, I'd look at Ultimate Campaign Kingdom Building and Books 2+ of Kingmaker for inspiration.
