Vial of Terra
The Vial of Terra was the pottery container used to hold the terraforming elixir which healed the land, at which its state was referred to as the Wasteland. The Vial of Terra was the major component Alara used during the Great Experiment, which proved successful, as we now have a living and breathing world today.
In recent times, rumors have been heard that suggests the Other Race which destroyed the world in the first place somehow survived, and that they began work on somehow re-destroying the land. Thus, research on the Vial has been renewed to counteract the perceived effects of what those of the Great Tree have termed Tainting.
