Gaia

The self-appointed stewards of the Earth who have bio-engineered Nature to defend itself against humanity ever populating the world again

Prologue
For many years we lived in shelters underground. We created sustainable towns; drilled tunnels, created farms; our kids went to school. Then the first hazmat teams went up. We had suits, machinery, plans. We would create domes, live on the surface, and work on restoring the world which had been lost.
