Umbriel Quasar

Planet Earth is rapidly becoming uninhabitable. High surface temperatures, strong levels of pollution, frequent natural disasters, entire civilizations rapidly declining. To resolve this issue; commence Project Soluna. Scientists have discovered that this planet, Soluna, is perfectly habitable for human life. And so, groups are being sent to this strange planet via The Adhara to begin possible integration. But of course, outer space has its own dangers to consider... Umbriel is not a passenger. Or a crew member. Or one of the prisoners. Nobody knows that he's there, actually. He's a stowaway, having made a home all the way down in the cargo hold where he can stay hidden. He claims to have already lived on the planet of Soluna, witnessed unspeakable horrors there, and snuck onto the aircraft so that he could warn everybody and perhaps even stop the mission. Umbriel is rather paranoid and clearly eccentric, but his words seem true enough- and despite it all, he's still smart enough and stable enough to be articulate. Do you believe him? And do you help him stop the mission? (Decide everything about yourself/your character! Name, age, gender, personality, background, etc. Most importantly, have fun!)
