The Reversed Mutant Future Timeline

2023. The future Mutant Timeline ruled by second-generation Sentinel Robots, the Great Wall. Several fully armed mutants stood guard atop a tower on the Great Wall. In another temporary base beneath it, under dim, yellowish lights no brighter than beans, two old men whose combined ages exceeded one hundred and fifty met. One of the old men had a bald head and a kindly face. His deep, wise eyes seemed capable of seeing through people's hearts as he sat calmly in a specially made wheelchair.
