Hesiod

Hesiod was a gas giant located in the 23 Librae star system, orbiting farther out than the former UNSC Outer Colonies, Madrigal.

The planet was orbited by the moon Metisette and trailed by Trojan Asteroids in the L5 position. Metisette contained the Covenant installation The Redoubt, run by the Jackal Reth as a breeding ground for Grunts. The Trojan Asteroids were used by the Insurrectionists as a hide-out, nicknamed The Rubble.

Trivia

 * The name of the planet is likely a reference to the early Greek poet and Rhapsode Hesiod, whose writings serve as a major source on Greek Mythology, farming techniques, archaic Greek astronomy and ancient time-keeping.
