The SextantForge cast

Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.

  1. Polaris Latitude from a star — the North Star’s height above your horizon IS your latitude
  2. Chrono Longitude from a clock — the gap between home noon and your noon, at 15° an hour
  3. Meridian One hour = 15° — Earth turns 360° in 24 hours, and the meridians follow
  4. Wayfinder The star compass — steer by stars that rise at the same bearing every night, no instruments at all
