Differences between Comet World and Real World

• There is no moon
• The transition from night to day, and day to night, is very fast, like a light switch being turned on or off. There is no twilight. There are pretty sunrises and sunsets, though.
• Rainbows appear at all sorts of powerful events, like volcanoes (orange) and great works of art (yellow), not just thunderstorms (blue).
• There aren't really compasses. It has something to do with there being six cardinal directions, rather than four.
• If you sail east from Gelan, past all the rainbowness, and then north, and then west, you don't hit the Broken Lands, you just get ocean.
