Guild House

The main building of the Guild is called the Pantheon. It is a wide space with counters for adventurers to talk with their advisors and also has a exchange area. There are also small meeting boxes where adventurers can talk one on one with their advisor without anyone else hearing them. Aside from that there is a library area.
The main goal of the Guild is to manage the monster threat created in the dungeon. Aside from this, the Guild buys magic stones, drop loot, and adventurer created maps of the dungeon. The Guild also provides weapons and armor to new adventurers who are just starting out.
The Guild staff also take the position of advisors for adventurers, often suggesting at what depth an adventurer should go in a dungeon in accordance to their level and skills, as well as warning them of any special dangers of certain floors and how to prepare against them. A staff member may be in charge of one or more adventurers.
Tower of Volkrun

The tower was built after the emergence of the dungeon in Rezion and is owned by the Guild. The first twenty floors are filled with Familia business, facilities, and money exchanges. Above that are living areas of the most prominent Gods in Rezion, known as the Private Rooms. There are some gods who prefer to live with their children, the most prominent being the goddess Athena.
Dungeon

The dungeon is a complex labyrinth of unknown length underneath the Tower of Volkrun.
The Dungeon is seemingly alive, spawning monsters from walls and ceilings and repairing itself on its own. It has an immense hatred of the Gods, immediately sealing the exits of a room if it detects one, and spawns a black version of a monster in order to kill them. The black monsters are far stronger than normal and display some intelligence, as the Black Wyvern looked around for its target. Despite this, it doesn't spawn another black monster after the first one is killed even if the God in question isn't dead.
The dungeon is vast with the floors becoming progressive larger the deeper it gets. It takes at least five days for a party to reach the 50th floor. While the upper floors can be soloed or done with a pair, starting from the middle floors one must create a party or risk death. There are several safety points in the dungeon where no monsters are born. The closest one being floor 17 that resembles an ocean-front.
Monster Colosseum

The Monster Colosseum is where non-adventurers can go to watch brave gladiators fight monsters. Due to the largest area in the center, it is often used for large festivals and other kind of performances that require a large stage. Fights between adventurers occur during tournaments, in which the grand prize is a large sum of Valis and a rare item.
The Heavenly Baths
A location in the upper floors of Valkrun, it is a extravagant bath house that is reserverd exclusively for the gods. The punishment for mortals entering the baths is quite severe.
Main Street
The largest street in Rezion that lead directly from the guild house to the Tower of Valkrun at the center of the city. Many merchant stalls and stores are set up along this street in hopes of drawing in adventurers either before or after their venture into the dungeon.
Rezion Shipyards

A large district filled with several docks and several warehouses, many adventures of the Poseidon Familia are hired onto vessels to protect them from monster attacks. Everything from large cargo ships to small sailing boats can be found here. It is also host the Poseidon Familia's own fleet of ships.
The Titled Orc
A tavern on the main street of Rezion that is often frequently by adventurers. The owner is said to be a retired level 6 adventurer so very few people ever skip out on their bills. Since it is favorited by both the Anubis and Athena Familias, it is the only place the two rivals seem to get along.
Barrel's Edge
The opposite side of the coin in comparission to The Titled Orc, Barrel's Edge is often a hang-out for the lower end of society mostly including criminals and other ruffians. Brawls are frequent in this tavern, with the loser having to pay the other's bill.
