Jeosyn was a planet in the galaxy. It had an extremely slow rotation period, about three months, which meant that days and nights were unusually long and that both caused temperature extremes. The side of the planet experiencing night was called the Shadow Side; the side experiencing day was the Sun Side. The Dreamers' headquarters was located on the Shadow Side of the planet.
The extinct sentient species which inhabited the planet created massive statues. Purple light shone out of their eye sockets, and they had strangely shaped heads with no hair, perfectly carved out human features, and were modestly dressed. The statues were hollow and filled with energetic crystals.
