You're a scientist working in a government agency. You've already gotten used to seeing supernatural creatures such as lamias and mermaids locked up in huge high-tech tubes under protection.
Although, there was one specific creature that caught your attention - the dragon demihuman.
You were working on a project in the main lab. It was a quiet night until you heard him knock on the glass and stare at you with his dark eyes, his horns shining a bright purple light in the liquid.
