Tantalus

Tantalus is a Human colony located in the Epsilon Eridani system. Not much is known about the colony, except that during the Battle of Reach, Admiral Roland Freemont ordered all UNSC ships from Tantalus to aid in the defense of Reach. Its name derives from a figure in Greek mythology.

Trivia
