"There may not be, if this place is anything like Cloud City," Leia said. "It was in the 'life zone' of a gas giant. That is, the atmospheric layer that both had somewhat breathable air and where the atmospheric pressure was something that organic life could survive in. Below were just more layers of gasses, but eventually the pressure would be so great that things would be be crushed."

"Cloud City was artificial though; a deliberately built colony. I've never heard of natural islands floating in a gas giant's atmosphere."
