Welltubers are a type of hardy plant native to the Storm-Path. Each stores vast amounts of slightly sweet liquid in their roots so that they can survive the Great Tempests overhead and regrow their stems and leaves after they pass. Often ten feet or more below the surface, these are typically located through the use of specially-trained dogs. In times of plenty, the inhabitants of the Trailblazer Republics are fond of using the sap of welltubers to make a popular form of alcohol.
Nearly all the mass of a welltuber is below the ground. Left undisturbed for years, their bulbous roots can reach weights of over a ton each.
Despite the rough conditions, welltubers are uniquely well-adapted to life in the Storm-Path, and in fact seem to be unable to grow elsewhere. Attempts to transplant them and encourage propagation in the Oasis and elsewhere have all met with failure.
