Tantalus

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

Trivia

 * The colony is likely named after a Tantalus of Greek mythology, or the city that bore his name.
