Calling Taxi

Taxi is stranded in an unknown land, full of nothing. She has no memories except for the ones right before dying. Or at least what should of been her dying. She is alone, and unbeknownst to her being called. Here every second is fatal. Every minutes lethal. Every hour is poison. Everyday deadly. Yet you learn to survive, because it's all you know. Here we meet Taxi, who is a psychologist definition of survival. She walks, gains knowledge and remembers. But who is Taxi?
