Two colossal empires, one unstoppable horizon. In the summer of 1402, the Anatolian plains became the ultimate staging ground for a catastrophic collision between Bayezid I, the "Thunderbolt" of the Ottoman Empire, and Timur, the fierce conqueror of the East.

This was no mere border dispute; it was a furious, existential struggle for absolute, undisputed hegemony all over. On this blood-soaked chessboard, fractured alliances splintered under the weight of ambition, and whispers of ultimate betrayal altered the very lineage of dynasties forever. The ultimate challenge lies ahead: to rewrite the collapse of an empire or to cement the supremacy of a new global conqueror.
