Classification: Mining World
Population: Approximately one-hundred million
Geography: A very cold climate, ranging from arctic environments at the poles to a snow-dusted steppe near the equator. Small pockets of warmer air created by underground hot springs provide the ecology for wild, alien foliage.
Government: The resources found on Mercogos Reach are important enough that several Imperial organizations have a claim on the rulership of the planet. However, the civilian contractors who toil in the mines are employees of the Ingot Corporation, ruled by a planetary governor.

Most of the human presence on the snow-covered world of Mercogos Reach is limited to small mining camps, each named for elements of the Periodic Table. Rare minerals here make this planet important enough that any sort of threat warrants a response from the Imperium despite its sparse population. There are rumors of alien artifacts located near the planets' poles as well as deep underground but those reports can not be confirmed.

Mercogos Reach is the site of a titanic conflict following a psychic scream and a tear in the fabric of reality as the warp buckled and belched.
