Elaaden: Desert Moon of the Heleus Cluster

Elaaden was a tidally locked desert moon in the Heleus Cluster of the Andromeda galaxy. A moistureless, sweltering expanse covered by countless sinkholes, it was one of the most hostile environments in the cluster, where unsheltered exposure to its sun meant a swift death. Despite these extremes it still supported life to a limited degree, and it became the site of the fledgling krogan colony of New Tuchanka.

A scorched world#

Elaaden was a desert moon of relentless heat and aridity. Its terrain was dominated by sinkholes and shifting seas of sand, with regions of dunes, hoodoo formations, and ancient structures left behind by the Remnant, the synthetic builders whose works dotted the cluster. The moon's environment was openly hostile to organic life. Anyone caught on its surface without shelter risked death in a matter of seconds, and the world's resources, above all water, were scarce enough to shape the lives of everyone who tried to settle there. Even so, life persisted at the margins, and the moon yielded mineral deposits that made it worth the danger to those willing to brave it.

A small trading post known as the Paradise supplied nearly all of the moon's water, giving it outsized importance among Elaaden's scattered communities. Elsewhere, abandoned mining facilities, isolated outposts, and improvised camps marked earlier attempts to live off the moon, and a sprawling canyon shelter called the Scavenger Flophouse housed the scavengers and gangs who ranged across the deserts.

New Tuchanka and the colonists#

Elaaden's most significant settlement was New Tuchanka, a colony established by the krogan who had come to Andromeda with the Nexus, the headquarters station of the settlers in the cluster. Named for the krogan homeworld, the colony was led by the overlord Nakmor Morda and stood adjacent to a site chosen for a separate outpost. The krogan presence anchored the moon's population and gave Elaaden a foothold of organized society amid the surrounding lawlessness. Figures tied to the wider settlement effort passed through the moon, among them the krogan veteran Nakmor Drack and the security specialist Liam Kosta, whose concerns reached to the founding of outposts on worlds like this one.

The Remnant vault#

Like several worlds of the cluster, Elaaden held a dormant Remnant vault, part of a network of ancient machinery capable of reshaping a planet's climate. When the vault was activated, the moon's atmosphere changed: cloud-forming particulates increased, ambient humidity rose, and rainfall became possible on a world that had been starved of moisture. The transformation did not make Elaaden gentle, for it remained brutally hot, but it eased the desperate scarcity of water that had defined life there, even as the newly humid air raised the danger of flash floods. With the change, New Tuchanka was reframed as a cooperative venture between the settlers and the krogan colony, a sign that the moon, however harsh, could be made to support a future.
