Yetmo

Yetmo (pronounced /jɛtməʊ/) is one of the four moons of Effluo. Purple in colouration, it is covered in extremely steep mountain regions. It contains a small robotised Sentinel facility used to monitor its planet, filled with telescopical cameras and such. It is worshipped by the Keidz on Effluo as a minor god. It is considered the God of Vigilance.

History
Shortly after Zaffron's system, and thus Effluo was discovered, it was clear that the system was either uncooperative or relatively uninteresting to both Galactic Empires. The Keidz refused to be colonized by the Sentinels, and were too dangerous or stupid to be of assistance to the Zealots. However, while the Zealots simply passed on, the Sentinels would build a small radar-and-camera facility on Yetmo to monitor the planet and the Keidz; one of two of Effluo's moons to receive this treatment, the other being Wokrom.
