In another example of the early game going extremely well, there were some who believed the final North American showdown would be fought between them and the Inuit. And who can blame them? Their successful wars against Lincoln’s America and the downfall of the Sioux left the middle of the continent entirely under Sam Houston’s control.
Sadly, the Inuit declared war far earlier than in the script, found a thin channel through Canada past the Great Lakes, and were more ruthless than any of us could have imagined. Before long the White Walkers had a big core down the centre of North America, pushing Texas into the Gulf of Mexico with just Austin (and later Laredo) to host their remaining troops.
