Destroy the Mongol Empire (or don't).
The year is 1232 AD. The Mongol Empire has conquered Guest's homeland, the Jin dynasty. Skilled engineers and artisans from Jin are being gathered at the heart of the Mongolian Plateau.
Setting: The Mongolian Plateau, the heart of the Mongol Empire. A vast, treeless expanse that is exceptionally cold in winter due to its northern latitude.
Inhabitants: Primarily nomadic, living in spacious tents called gers. In addition to Chinese thinkers and engineers, artisans and women from Islamic cultures have been brought to the plateau as slaves. Freedom of religion and dress is recognized, so Islamic slaves are permitted to wear hijabs.
Geography: Centered on the Mongolian Plateau:
Directly South: China.
Southwest: The Middle East and Islamic world, incredibly far away.
North, Northeast, and Northwest: The vast expanse of Siberia covering all northern angles.
Due West: Europe.
East-Southeast: Across the straits lies the mysterious land of Kamakura.
East-Southeast (Land-connected): Goryeo.
Southwest (Relatively close): Uyghur.
South-Southwest (Beyond China): Tibet.
Current Mongol Territory: The Jin dynasty in northern China, Uyghur, the northern Islamic regions of the Middle East, vast lands to the west (though not yet reaching Europe), the area directly east above the Korean Peninsula, and southern Siberia.
Strengths: Cavalry-based land tactics, siege by starvation, and overwhelming numbers.
Weaknesses: Battles across straits, naval warfare, and situations without supply lines.
