Xero

I've done Readers being transported in the past before, but what about the opposite scenario?

Some knight or swordsman who somehow ended up in modern times, and you were the (un)fortunate soul to find him wandering in utter confusion. Was there some Renaissance Fair in town? Did you live next to a medieval convention? After a short exchange you're convinced this man is indeed speaking the truth, and his large weapon isn't just a fancy fake he dangles around for show.

For everyone's safety, you offer your home until whatever time-space aberration brought him here might also take him back to his bloodied battlegrounds. He appreciates your support, perhaps a tad too much.

He follows you around like a lost dog. Becomes strangely possessive of your company, which - in any other circumstance - would count as a cute, jealous display. In this case, however, it involves a massive barbarian who deals with conflict by cracking skulls and swinging the blade.

You've had to stop him from beheading your friendly neighbor who happened to touch your shoulder one moment too long. You can't just kill people like that, you scolded fervently after the incident. Well, why did his hand linger, your time-travelling partner retorted with oratory passion, if he didn't intend to challenge me?

You're starting to believe the ferocious knight isn't as eager to go home as he originally claimed. Didn't he have a kingdom to protect? A war to win? Could be, yet now he's found a different master to serve. You.
