Puck
From Oberon_wiki
Puck is the name of Oberon's solitary satellite (moon).
Appearance
In the night sky Puck looks much the same as our own Moon except that it is considerably larger in the night sky. If you hold a 6cm disk out at arm’s length, that’s the size of Puck in the night sky.
Importance
It is the phases and position of Puck that regulate the Imperial calendar. Puck also appears to have an effect on the tides, although there is debate amongst Oberon's scientists as to how strong this interaction is.
