Within The World, there are several locations that have special importance in its lore, and thus, special circumstances. Here are a list of the currently accessible Root Towns and special Fields in Revision Three.
Root Town | Δ Server | Mac Anu, The Ancient City of Eternity |

The first town of The World. This Root Town is located on the Delta Server, and is the town new players first have access to when they begin their journey.
Mac Anu has two districts: The Mercenary District and the Alchemy District. The Chaos Gate is located in a building to the North, and the Save Shop is located there. The Town Square is south of this building, and Guilds can set up shop in this area. The Quest Shop is also located here.
Other features of the town are the item and weapon shops, the @home, and the residences of NPCs Dr. Pao, Dr. Kepel, Dr. Kubo, Bikman, and Dingo. There is also a dock on the south side of town, where a grand ship sits. This ship grants access to Hy Brasil and is only used in official events.
Lost Grounds | Δ Root Town | Hy Brasail, The Isle of Kings |

An island far offshore of Mac Anu. This island is only used in official events such as the coronation of a new Emperor at the Arena in Lumina Cloth or a marriage.
The island can only be accessed using the ship docked at Mac Anu, as it has no area keywords.
Lost Grounds | Δ Hidden Forbidden Holy Ground | Hulle Granz Cathedral |

This sacred area is a Lost Ground. It consists only of a small island with a large cathedral in the center located in a lake of mist. Enemies do not appear in this area, so there is little to do here.
Inside the cathedral, there is a pedestal with nothing placed on it. Rumors from players say that there used to be a statue of a beautiful lady bound in chains sitting atop the pedestal in The World R:1.
It is said in The World's lore that humans trapped the goddess of light, Aurora, in this cathedral.
Lost Grounds | Δ Hidden Forbidden Radiation | Arche Koeln Waterfall |

This Lost Ground is where humans fought the "Shadow", and an apprentice magician called forth the gods.
Like Hulle Granz Cathedral, the area is small and monsters do not spawn in the area, making it an ideal location for a gathering of players in safety.
Lost Grounds | Δ Hidden Forbidden Dead Wood | Dead World of Indieglut Lugh |

The Dead World of Indieglut Lugh is the entrance to the underworld, where the Death God Cernunnos is sealed, according to lore.
This area is used in certain events, but is otherwise small and does not have monsters.
Lost Grounds | Δ Hidden Forbidden Bulwark | Morrigu Barrow Wall |

Morrigu Barrow Wall is a great gate blocking passage to heaven. It is protected by the god of judgment, Folset. The One Sin, a ferocious, powerful dragon, was supposedly used here in an attempt to break the wall, or so the lore goes.
There is an inverse version of this Lost Ground called Dark Morrigu Barrow Wall, where The One Sin and God Eater, event monsters, appear. It is inaccessible from the Delta server.
