Helpfully highlighted here, Sejong (Korea) will show Trigger (Darkhan, of Yakutia) mercy, leaving his descendants to ride out Ragnarok beneath the Arctic ice. Now the Korean despot just needs to push that Mongol advanced destroyer out of the way to stake his claim to longest aquatic road.
Meanwhile, aboard the orphaned Yakut sub, years pass. The residents mingle, fall in love, marry and procreate, grow old and leave the sub to the next generation and the next and the next. Boredom overwhelms, and the descendants of the great leader finally dream up a simulated spheroid where doomed and fictitious civilizations dance and slaughter for the sub's delight. After years of careful effort, desperate bugfixes, and frighteningly intense devotion, the Boers win.
