Mantallor

Little is known by the Imperium of this dismal system beyond the existence of two large rocky worlds orbiting a dull red star. Colonised by Tau of the Brightsword Protectorate, the planets Phael and Mantallor orbit close to the solar mass, and both tidelocked planets are bathed in heat, dull red light and waves of radiation.

The industrious colonists inhabit the narrow inhabitable zone of the solar terminator ring bordering the night and day sides of the planets.
