Ensolica

Ensolica was a planet covered almost entirely by frozen tundra on its continents and thick ice sheets on its oceans. Along its equator lay a tiny "tropical" strip of coniferous forest and frigid sea.

The planet's humanoid inhabitants, the Ensos, built cities by chiseling them into the ice. In fact, an end to the Ensolican ice age would mean the certain destruction of centuries of priceless architecture. Because of the hydroponic expertise of the Ensos, Ensolica attracted the attention of corporations such as Alderaan Biotics and Tusus Comestibles.
