The Empire I Built Isn't That Austro-Hungarian Empire

A hardcore fan of single-player war games stays up all night battling, then unexpectedly transmigrates to the final days of the Austro-Hungarian Empire. He has barely gotten used to being addressed as Your Highness when he learns that the empire has only a week left. What is he supposed to do? While racing to survive and prepare for modern enemies, he must also contend with the mysterious accessory of an ancient rock python and outwit the dark forces left behind by medieval Europe. In the end, he finds a perfect love beyond compare.
