The Scriptures say that the Galleon Meadow is where the Thirteen Tribes began their respective journeys away from Kobol aboard a "great ship" called the "galleon". Twelve went on to form the Twelve Colonies of Kobol, while the thirteenth went in a different direction to Earth.
The meadow's exact location is known, and it is the nearest landmark on the path to the Tomb of Athena. From the Meadow one can see the High Road, a rocky ridge leading in the direction of the tomb.
The Faction that sought the Tomb landed here from the Astral Queen following the cooperative Caprica copy of Cylon infiltrator Sharon Valerii on their journey (Home, Part I).
