One Mysterious Substance

Chase was walking to school one cold morning, it was late October, and the essence of fall had already settled. He sighed, a breath of cold air escaping his mouth as steam, he paced down the street slowly.

Chase was a little above average guy, he was pretty good looking in most cases. Six foot tall and 18 years old, a solid build, and medium black hair. He was in his usual attire, a standard shirt and denim jeans, but with an added jacket to compensate for the cold.

As he continued along his way to school, just a couple minutes away, a man approached him from an alleyway. At first he ignored him, but the man continued to press towards him, obviously trying to get his attention, Chase turned,

"What do you want?" He asked, a little creeped out and a little frustrated by the old geezer. The man smiled an almost toothless smile, his eyes squinting as he brushed the long white hair out of his face.
"I am here to bestow upon you the gift of control." The old man spoke like a prophet, a mage of the old days, Chase was confused, and squinted his eyes to show this. As soon as he did this, the man pulled something from his long beige jacket pocket. A small bottle, with a somewhat cloudy liquid contained inside.

"Have someone drink this, and they will fall under the control of the first person they see." He said, giggling childishly as he handed Chase, who accepted it reluctantly. He shrugged, looked down at the bottle, then looked back to see the old man had vanished.
"Okay..." He said, looking down at the vial. It had no name, no writing of any sort, he put it in his backpack and continued on his way to school.
