Galena

Citadel of Knope
The Citadel of Knope protects your colony by redirecting damage of ships to itself whenever your defense force is unable to, meaning it is the last line of your defense. When it does this it loses a level. However, if it survives the impact it automatically creates a mirror replica of the ship that damaged it, thus giving the defender the ship that just attacked them.
Kalavian Ruins
The Kalavian Ruins were left behind by the Great Race that once inhabited the Lacuna Expanse. No one knows exactly what did it do or was designed to do, but it does resemble an ancient theatre. Anyway, they still hold great mystery and wonder today, attracting tourists, while bringing a sense of pride for citizens. If you were to find the Ruins on your planet, they would greatly increase the happiness of your citizens.
Ravine
A ravine is formed during movements of the planet's plates. It is too hot down there so it can only act as a natural waste sequestration well, which can store up to 100,000 waste at its first level.
