What country is Celestia?

Excuse me, I've come across the name "Celestia" in some recent financial news articles related to cryptocurrency. However, I'm rather perplexed as to its exact location. Could you possibly enlighten me on what country Celestia is located in? Is it a real-world country, or perhaps a fictional place referenced in the crypto world? If it's a real country, I'd appreciate any details you could provide on its geographical location, political system, and perhaps even its economic standing, especially in terms of cryptocurrency adoption and regulation. Thank you for your time and assistance in clarifying this matter.
