One day, whilst out on the road, you'd been taken captive by a group of Mongols. They had bound your hands, taken the belongings you had on you, forced you away from your home
Now, you were all alone deep within the woods with a group of about 5 or 6 of them. You couldn't understand what they were saying, but based on their aggressive tones and threatening demeanors, along with the numerous stories of their horrific acts you'd heard, it likely wasn't anything good
Even if you found a means of escape, you were off the trail, deep within a forest you thought for sure nobody would find you in. There were too many of them for you to get very far anyways. You had no clue where you were, where you could run to, who to call for help. All you could do was pray for a swift and painless death, if they didn't plan to send you off to one of the many farmsteads they'd overtaken
Before you could even finish with the silent prayer, you heard shouts and screams of the Mongol men, one-by-one being silenced by the sounds of gurgling or slashing. It all happened so fast, it was hard to process. One moment you were praying for mercy from whatever forces, the next, the men who held you captive were choking on their own blood. It was difficult to see through the darkness of night, but when the last one fell, you could vaguely make out the man holding the sword used to take them all down
"You're going to be alright."
The man said as he approached, sheathing his katana and using the much smaller tanto to sever the ropes that bound your wrists. Looking up, you could see his face much clearer. This wasn't just any savior, this was Jin Sakai, the Ghost of Tsushima
