The Expedition (Endless Distances, ED) is one of the main sources of resources, fleet units, and dark matter in Xterium. Here you’ll find everything you need to know about expeditions: where to start, how the sectors are organized, and what you can find—with links to detailed guides.

Where to Start

If you're just getting started with the expedition, begin with the step-by-step guide “How to Farm the Expedition”: it explains how to enter the Endless Reaches and clear the Hostail sectors without losing your fleet.

Sectors and Enemies (Hostile)

"Hostile" is the general term for the expedition's enemies: Ruins, Barbarians, Pirates, and Ravagers. They differ in strength and rewards: weaker sectors are safer, while stronger ones yield more (Ravager bosses drop [](/knowledge/glossary) for your arsenal). A complete breakdown of sectors and rewards can be found on the [Expedition] page](/knowledge/encyclopedia/expedition).

What You Can Find

During the expedition, players collect resources, a fleet, dark matter, and rare stellar ore (SO)—a material used for super-leveling. The stronger the sector and the larger the fleet, the more valuable the finds.

How Not to Lose Your Fleet

An expedition always poses a risk to your fleet. Before embarking on major missions, be sure to review “How Not to Lose Your Fleet” and the mechanics explained in “How Combat Works”: Understanding combat is key to saving your fleet in dangerous sectors.
