Wandrella were giant worms native to the plains and swamps of the planet Mimban, also known as Circarpous V, located in the Circarpous system. Mimban was a sparsely populated, largely unexplored world, allowing the Wandrella to have free roam over much of the planet. Notorious for their simple intelligence and rudimentary thinking, the Wandrella were omnivores with only basic tactics in hunting, demonstrated by their charging headlong after prey, flattening anything in their path.
