[1.0] Below Earth

A clash between species eons ago drove one of them underground, where they delved, dwelled, and found many things. But now, those who live on the surface have developed well enough to spelunk. However, those below have developed far more than mere technology... - Be one of many inhabitants of the Earth, able to explore both the Surface and the Underground for yourself; - Use powers and/or cybernetic enhancements for your own goals: fame, fortune, order or chaos; - Discover ancient and not-so ancient ruins which confirm the turbulent past of the world's inhabitants, and collect their artifacts.
