        There was a hemispherical blue structure at one end of the compound, and a pavilion nearby.  A table sat under the pavilion, with a very odd chair next to it.  Like all the structures in the camp, it seemed to be made of cloth, and of flimsy construction.  Each of the buildings had ropes pulled tight to the ground, obviously to stabilize them.  However—even to Lyra’s untrained eye—it was apparent that if he had simply used larger supports, he wouldn’t have needed the guy lines.  There were certainly enough trees around to build a real house, so why had he settled on these?
