The Dru Nation is the one with the oldest recorded history and buildings. They lived in the cool northern regions of the planet. In the time before space flight the Dru Nation had Emperors who had massive palaces that were similar to the Ancient Egyptian pharaohs of Old Earth.
They are known for their great art, literature, architecture and fine jewellery.
Their traditional dress is very conservative, covering themselves with animal furs and thick fabrics.
Persenopone was their first exo-solar colony.
