Eleusis

Mining city in desert mountains on Mercury.

Eleusis emerges in the Red Rising Saga as a vital mining city nestled in the harsh desert mountains of Mercury, serving as a strategic hub for resource extraction amid the escalating Solar War. In Dark Age, it becomes a focal point of conflict, highlighting the brutal stakes of the Society's desperate bid to harness Mercury's helium-3 reserves against the Rising's onslaught. Though its role is confined to this pivotal volume, Eleusis underscores the saga's themes of industrial exploitation and territorial warfare in the outer rim of the empire.
