@ Guardian: if it were up to me and I didn't mind creating a parallel timeline...
I'd probably give the natives three technologies they could probably handle at their development level.
Glass/lens making.
Gunpowder
Hot air Baloons. (maybe)

I think if nothing else the gunpowder would give them an edge against early european settlers.
giving them primitive flight and the ability to make long ranged weapons using existing tools well...
yeah lol.
there were more individual nations on this continent than there are in the world today, and just as many unique languages, I'd like to see the manifesters meet a foe that's able to actually fight back without needing to become like them.
