Map 456 field notes

MyStonerville players turn general strategy into local, versioned knowledge.

  • The characters in Players are community identities, not official game enforcers.
  • Use faction chat to preserve local tactics and diplomatic changes.
  • Date every guide and verify numbers after game updates.
  • Share corrections rather than presenting estimates as official values.
