How It All Goes Down
- Twoflower and Rincewind stare at something beautiful, and a voice behind them says it's the Rimbow.
- Twoflower introduces the voice as Tethis, a sea troll, but Rincewind passes on turning around to see him for the sake of his already frayed sanity.
- He's told they were saved by the Circumfence, a giant net circling much of Discworld's edge.
- The ship travels across the Circumfence toward Tethis's home, and Rincewind observes the Rimbow and the shimmering of the eight color, octarine, within it.
