Casbin is a classic "pre-garden" terrestrial world, with conditions similar to those on Earth millions of years ago. Its hot, humid atmosphere is mainly composed of nitrogen and carbon dioxide. An increasing amount of the surface is covered by simple lichen and algae. Should no unexpected calamity occur, these tiny plants will change the atmosphere to an Earth-like nitrogen-oxygen mix over the next few millennia.
Due to its potential for future habitability, Casbin has been designated a Sanctuary World by the Citadel Council. Landing is prohibited by law, and any disturbance of the fragile young ecosystem will result in harsh fines and imprisonment.
At present, the planet is passing through the debris trail of a long-period comet.
- Note: The Mako can land here. There are deposits of samarium, uranium and gold. There is a geth outpost for UNC: Geth Incursions. There is also a crashed probe to be salvaged and a Salarian ID Tag can also be recovered.
