The Island Impeller was a creation of Teslex, the technologocially advanced colony that descended from the Warforged colony of The Sky Net.
It was known as early as 3/16/190 CR that the Impeller had critical faults that would lead to its failure, and ultimately the demise of the island of Cof alongside its inhabitants.
The impeller was repaired by a team of Troubleshooters from Alpha Complex including Pixel, Evo, Ezra, and countless allies of their secret societies that they had hoarded "IOU"s from. Only with the combined IOU expedenture of the heroic troubleshooters were they able to repair the impeller and save the island.
