Loch Esmeralda

Loch on Mars.

Loch Esmeralda is a strategic Martian lake that first appears in Dark Age as a critical battleground during the Solar Republic's civil war. Its emergence marks a shift from orbital and urban warfare to contested planetary terrain, highlighting the Republic's struggle to maintain control over Mars itself. The loch's significance grows as it becomes emblematic of the broader conflict between Darrow's forces and the rising threat of Atalantia and the Society remnant.
