Regarding text on the corresponding maps of Windurst areas (and probably some NPC dialog here and there):
  • Odin's Gate:
    • Exits Windurst Waters to the north.
    • Odin's constellation is to the north.
  • Leviathan's Gate:
    • Exits Windurst Woods to the east.
    • Leviathan's constellation is to the west.
  • Shiva's Gate:
    • Exits Port Windurst to the west.
    • Shiva's constellation is to the east.

Either Leviathan's and Shiva's Gates should have their names exchanged, or Odin's Gate should be renamed to Titan's Gate.

The error probably comes from referencing the star charts viewable in-game. They adhere to the real-world custom of placing east on the left and west on the right, in contrast to maps (think of it as looking up at the stars versus looking down at the ground).
