The planet Maddules is one of the three large gas planets in the far reaches of the Metellos System. Due to its gaseous nature, it is extremely light, but its atmosphere is surprisingly thick for a gas planet, which has stumped scientists for ages. However, the atmosphere holds a mixture of toxins which makes it difficult, though not impossible, for humans to inhabit. Most species tend to avoid the planet as the gases in the atmosphere travel at extremely high speeds, with enough force to knock over a full-grown Wookiee.
