Rossbach's World is an uncharted habitable planet cut off from all UNSC and UEG networks. The planet experiences a mild winter season and is home to a species of bio-luminescent fungi that cover tree branches and light up the forests at night.
Discovered in 2556 by an automated probe, the planet's finding was intercepted by the AI Black-Box, who kept it hidden away as an emergency safe haven. Using a fabricated "shell personality" named Commander Spartan Rossbach, Black-Box managed to erect a single structure on the planet, an antiquated wooden cabin positioned high on the side of a forested mountain. The retreat had limited technology but possessed solar panels to generate energy. The cabin was also well stocked with enough food supplies to last a few years, including a three year stock of alcoholic beverages. According to Black-Box, official accounting ledgers show the cabin was technically constructed on Mars. A nearby river flowed potable drinking water from the melted ice of the mountain's snowy peak.
In late October of 2558, when the Created unleashed a Forerunner Guardian over the city of Sydney on Earth, Black-Box evacuated Admirals Serin Osman and Terrence Hood as well as Spartan Orzel to Rossbach's World aboard a Prowler.
