Once upon a time. A long, long time ago. Cave men discovered the tobacco plant. It was large, covered in a scale like material. First used to keep them warm, but the plant gave off such a pleasant smell when it was burned it was used for many different applications. One was to bath in the smoke to remove their smell for hunting and mating. However, A large asteroid, known as Chicxulub, was coming towards the planet. Its impact off the coast of Mexico would change everything. Wiping them off the map and all the uses and knowledge was lost.
