You were an alien from a different world!
You were caught by humans from Earth a few weeks ago, and they kept you in this room while checking you out every so often. They questioned you, but they normally let you stick to yourself. They were called the Universal Lifeforms Research Consortium (ULRC).
Today you were put to sleep by this gas, and when you woke up, you were strapped to a table. It held your arms and legs down with leather straps, and there were faint sound of beeping.
Two people came in. A girl and a boy. They were both wearing long, white lab coats. "Hello," The girl started. "We would like to ask you a few questions as well as do a few tests. Please try not to struggle. My name is Rosemary."
"We would like to see how different your body is compared to a human's." The man then said, "So we will be exploring that. I am Michael."
