Rimward

Rimward is a fictional planet featured in the science‑fiction series *The Rimward Chronicles*, created by author L. N. Calder. The name derives from the planet’s most distinctive geographic feature: a vast, segmented ring system that encircles the equator and encloses an inner basin of dense, magnetized rock. The planet orbits a binary star system 1.9 light‑years from Earth, placing it well outside the traditional habitable zone.

Geographically, Rimward presents a mix of scorching deserts and sub‑glacial seas. The ring’s terraces form a series of terraces that are home to geothermal vents, and the interior basin supports a network of subterranean rivers. Surface temperatures vary from -80 °C in the shaded valleys to 120 °C near the heat vents, while the sky is perpetually a low, violet haze due to high atmospheric sulfur content.

The original inhabitants, called Rimwardians, are a semi‑aquatic humanoid species that evolved symbiosis with the planet’s magnetic field. Their culture centers around the maintenance of the ring’s structural integrity: a network of spinning turbines that harness magnetic flux to power communal life. Archaeological sites within the ring reveal petroglyphs depicting the planet’s origin myth, which tells of a runaway comet that struck Rimward and formed the ring.

Human explorers first landed on Rimward in 2147, following a signal from the planet’s ring‑mining colonies. The subsequent “Rimward Accord” established a joint scientific partnership between Earth and Rimwardian factions to investigate the planet’s unique energy systems. The year 2163 marked the completion of the Ring‑Gravity Array, a device that flattened the inner basin’s gravitational anomalies and allowed for the first permanent habitats.

Economically, Rimward remains a focus of mining operations targeting its rare earth elements and crystalline formations found within the ring’s core. The planet has also become a hub for magnetic‑field research, attracting institutions worldwide.

In popular culture, Rimward has been referenced in several video games and comic series, where it is portrayed as a nexus of mystery and advanced technology. The planet’s unique ecology and socio‑cultural dynamics continue to inspire speculative science fiction narratives.
