Blue Sword

In the year 241 of the Sixth Age, Constantinople was in turmoil.
Emperor Constantine personally led the expedition and the entire army was wiped out. With the power of great victory, the pagan empire annexed the entire eastern territory of the empire, and its troops were directed towards the capital.
The 17-year-old imperial princess Theodora ascended the throne at a critical moment, and what was in front of her was a mess that was already riddled with holes.
Rome is about to fall.
………………
The gears of fate turned crazily, and a certain time traveler appeared on the streets of Constantinople.
"According to the original plot, Constantinople will fall sooner or later." He thought for a moment.
"It's better to abduct the Queen first."
