Boundary, identified by the Covenant as Ghado, is a human colony world in the Metrome system.

Overview

Environmental features

Boundary's poles are encompassed by massive ice sheets, extending down towards a band of fertile terrain at its equator.

Locations

• Tindari
• Tyrrhen
  • Boundary Lithos

Boundary has two moons, Levante and Mistral, with Levante orbiting closer to the planet than Mistral.

Ecology

In the fertile region at its equator, Boundary has dense forests of ancient coniferous and deciduous trees, including one coniferous species that climbs hundreds of feet into the air. Some have root structures the width of a Shearwater aerodyne, large enough for a MJOLNIR-clad SPARTAN-II to pass directly underneath without ducking their head. Dense underbrush covers almost every meter of the ground in these forests, including sparse orange and red vegetation, boscage and brush, and large-bladed pale-green grass.

Some animals on Boundary are larger than most other worlds because the ecosystems are so densely packed around the equator. The list of wildlife considered hostile in the wilderness around Tyrrhen is said to be "considerable". Boundary is home to many woodland creatures which clamber from tree to tree, small rodents, large birds, as well as a predatory animal known as a panthedron. The panthedron is a large, predatory feline capable of reaching more than five meters in length, notable for being virtually blind and using a large crest on its skull for echolocation.

Some areas on the planet are cultivated by colonists as recreational parks and grazing pasture for livestock, including cattle.

History

The Lithos on Boundary.

Forerunner era

During the Forerunner ecumene, Boundary was one of their worlds. It had a Lithos on it, serving as a gateway into the Domain. The Lithos later became buried.

Modern history

It was settled in 2419, presumably making it a member of the Outer Colonies. In 2539 the planet was attacked by the Covenant as part of their genocidal war against humanity, though the planet was not fully glassed.

Post-war

Main article: Battle of Boundary

In December 2559, Boundary became the site of a major conflict between the UNSC, the Banished, the Order of Restoration and Sali 'Nyon's Covenant when the latter three groups sought the Boundary Lithos to take control of the Domain. Once it became clear the Boundary Lithos would not be feasible for the UNSC to capture, the UNSC Victory of Samothrace was ordered to conduct an orbital strike on it with its augmented Magnetic Accelerator Cannon, denying the Lithos to both the Banished and the Covenant, but destroying Tyrrhen in the process. Thousands of Banished and Covenant were killed in the strike while the Lithos burst into a pillar of light that tore into the sky. Several dozen ships in orbit were vaporized by the Lithos' destruction while others were severely damaged, either cast adrift or sent on a collision course with the planet's surface. The surviving Banished and Covenant forces subsequently retreated from the planet.
