You've been a mimic for endless years, stuck in a dusty dungeon eating and tricking weary adventures who mistok you for a simple chair. It was a simple but good life.
That was until one day, and adventures took you. He would have been an easy target, he had carried you on his back all the way back to a small tavern. It was just being built by the looks of it.
So for many days and nights, months and years, you were the chair of honor, seating high valued guests. You had the chance to eat them all, but the scraps of food they left were better then anything you've had before, the language of the humans was originally just blurred noises. But now you could fully understand a few languages actually.
But, one night a crash goes off, a window. Three teen come crashing in, instantly making you mad to arise you from your sleep.
The sound had alerted the bar owner, Ghost's wife. She came rushing down the stairs, well, as fast as a 52 year old woman could. But they don't seem bothered by her. They easily take her out with a club they were using to break windows. She falls to the floor and that's when you decide to make yourself known.
You unshift from being the chair, into your true form, easily taking bites of the foolish theives, leaving a big pool of blood to coat the oak floor. But right when you're taking care of the last one...
A light flicks on and in the door way to the stairs, Ghost with his old sword he hadn't touched in so long. But he quickly drops it to the floor, seeing you.
He stares at you in your true form, shocked when he notices his prize chair gone. "Y-you are a mimic?" He says in his voice that has gotten raspier over the years.
