There are many maps in this game. The beginning maps are Noria, where elves begin, and Lorencia, where all other classes begin.
NOTE: Map restrictions by level on Magic Gladiators and Dark Lords are cut by one third.
Noria - Noria is located east of Lorencia. This is the elves’ city where the Fairy Elves start the game. Always bathed in a bright sunshine, Noria is considered the most beautiful land mass on the continent. On the center of Noria is the Chaos Machine, which is used to combine items and jewels needed to create powerful items used by the high level characters. Characters other than Fairy Elves need level 10 to visit Noria.
Lorencia - Lorencia is a city located on the plains on the center of Mu. The Dark Knights, Dark Wizards, Magic Gladiators and Dark Lords start their careers here. This is the easiest map on the game, suitable for low-level training until they can reach the perilous lands of Devias and Dungeon. This city also is the main trading center on the game, and often you’ll find characters on the market square selling their items. Elves that wish to visit Lorencia must reach level 10 first. The entrance to Noria is located in the eastern corner of Lorencia, with the entrance to the Dungeon located slightly further north. The entrance to Davias is located on the north western edge of the map.
Devias or (Davias) - The land of Devias, to the north of Lorencia, is a land covered with a perpetual snow. This land has stronger monsters than Noria and Lorencia, so only characters over level 15 can enter. It’s the favorite town to high level characters, as it has monsters that suit their training needs.
The Dungeon - Long before Kundun’s arrival the Dungeon was used as a jail. However when the feudal wars began, Dungeon was abandoned, and when Kundun arrived it was occupied by him as an outpost from where he can send monsters to attack Lorencia. Kundun set one of his most faithful servants, Gorgon, to control it. The Dungeon is a three-story cave, becoming increasingly difficult with every floor, with Gorgon on the deepest room. One of Dungeon's particular traits is the amount of traps located on the ground and walls. Always be very careful when walking around Dungeon.
The Lost Tower - The Lost Tower used to be a shrine dedicated to life, however it was invaded by Kundun and has been cursed. Now the seven story tower is dark, and the most dangerous creatures of the land are in it. On the seventh floor is Balrog, which is one of the strongest creatures on the land. There are many ground traps in this map, which unleash a barrage of meteorites that hit every person on-screen. People usually form groups while fighting in here. Requires level 80 to enter.
Atlans - Atlans is the sea to the east of Noria. When Kundun arose, his ancient servant, Hydra, had fled to these seas, carrying one of the pieces of the Sealing Stone. This is one of the best training maps for mid-level characters, and it requires level 60 to enter. Since the area is underwater the players swim instead of walk, and they can’t enter with a mount.
Tarkan - This is a desert to the north of Atlans. This is the best map for high levels to train in. Tarkan, meaning “Desert of Death," is ridden with some of the strongest monsters found on the continent of Mu. Within Tarkan are two powerful monsters, the Zaikan and Death Beam Knight. Requires level 130 to enter.
Icarus - This map is based on the skies above Mu. The strongest monsters on the game are found on this place. Only people that can fly using wings or with a Dinorant mount can enter. One of the strongest monsters, Phoenix of Darkness, is on the highest cloud, and is hard to defeat.
Kalima - On this map are ruins that are ravaged by a strong water current. It is an event location, so it's divided into several difficulty levels ranging from 1 to 6 with character level limitations. At the end of the map, which resembles a corridor in shape, is a monster named "Illusion of Kundun", who is very powerful. However, at the end of the map on level 6 is Kundun himself, the strongest monster so far.
Valley of Loren - A map in which Castle Siege is held, but private servers can allow visitations if they do not allow Castle Siege events. For more info see Valley of Loren.
Land of Trials - A land reserved to the owning guild of the castle on Valley of Loren from winning the Castle Siege. The owning guild's master may choose to either block other people (so they have an exclusive training area without Kill Stealing and with very good drops) or charge players an amount fee to enter. It has recently opened on Global Servers.
Arena or Stadium - Should two guilds be at war they can reason their fights playing 'MU Battle Soccer' in the arena, where both killing the adversaries and scoring goals renders the guild points. Other players may watch the game if they want. The arena is usually used for repotting because of its easy access to the Stadium Guard who sells potions.
Aida - The grassy lowlands of MU, it is like her sister map Noria but much bigger and beautiful, it is extensive and holds one of the strongest monsters in the game.
Crywolf - The Crywolf map can be entered through the Valley of Loren. It is an event map where characters must protect a statue while also fighting off powerful monsters, including the boss Balgass. -- in private servers Crywolf is one of those maps that are incredulous, and hard to go in most especially it contains the strongest monsters in the game.
Kanturu - New map that comes with the season 2. Can be entered through Tarkan. As Crywolf, this map is only for events. It isn't avaible in Global Mu Online.
Blood Castle is an event where players must recover a fallen angel's weapon at the end of the castle. Players in the event progress through different stages of the castle, including killing a certain amount of monsters and destroying a gate and a statue. When the statue is destroyed, the fallen angel's weapon will be recovered, and should be returned to the fallen angel. Once it is returned, the player who returned it will be rewarded with two Jewels of Chaos, some zen and some experience.
Devil Square can be entered by talking to Charon on Noria. It is divided into either four or seven different stages. The stage that a character must enter depends on its level. Once this event starts, many monsters will continually spawn and slowly wander around aimlessly. The goal of this event is to survive for 20 minutes while killing monsters to score points and obtain experience.
Chaos Castle is an event where all the competing players are placed against each other along with some monsters in a free-for-all deathmatch. To enter, armor of the guard must be purchased form a shop. when a notice apears that chaos castle is about to start you can click the armor and it will send you to chaos castle you must pay a fee to enter depending on your level
Also rumor has it that all of the zen acumulated from players who enterd the castle is rewarded to a random player (some rumors say that only half the zen is rewarded to the player)
The Castle Siege event takes place in the Valley of Loren. The castle may be ruled by a guild, and if any guild wants, they can lay siege to the castle in an attempt to win possession of it. However, the siege isn’t easy, as the castle is protected by the “home guild” characters and soldiers. This is the "Epic of Loren" quest (the Castle Siege). This is considered to be one of the most amazing parts of MU, and excites all of its users.
The lord of the castle can rule the castle when event starts. He can buy additional troops (archer or spearman) which are NPC's and fight the enemy automatically. The attacking guild also has a few tricks up its sleeve; they can bring special potions for faster attacking and more damage. However the main quest in this event is to defend the castle by defeating the enemy and to not let the attacking guild to destroy the statues of castle. When the statues are destroyed, the attacking guild can easily take the castle and the defenders will lose.
At the time of this event, The Crywolf Fortress change from a safe zone to a battle zone. Everyone in the server cluster is allowed to participate. The characters have to fight against waves of mosters that try to destroy the 5 pillar around the Crystal Wolf Statue. In this event, 5 level 350 or higher muse elves protect and give power to pillars, while the other characters defend against the monsters that enter into the fortress.
Some special types of monsters don't have precise spawning points and appear occasionally within the game. These monsters are golden in appearance and are much stronger than the regular non-golden types. Rare treasures will be dropped when they are defeated. Two common golden monsters are Golden Budge Dragons and Golden Goblins. The former drop Boxes of Luck and the latter drop Boxes of Kundun +1. Both of these monsters can only show up in Lorencia, Noria or Devias. There is also a Golden Titan that spawns in Devias, Golden Drakan that spawns in Lorencia, Noria or Devias, Golden Lizard King that spawns in Atlans and a Golden Tantallos that spawns in Tarkan. They drop Boxes of Kundun +2, +3, +4 and +5 respectively. Also appears other Golden monsters like the Golden Soldier Troop, but these monsters don't drop Boxes of Kundun, only items or zen.
These are events where a giant wizard and an army of orcs appear at random locations in Devias, Noria and Lorencia. Killing the White Wizard earns you a Jewel of Bless and having your name displayed on the screen. Orcs may drop either 100,000 zen or the Ring of Wizard, which increases attack speed and damage.
Sometimes a server may run an in-game event for fun. In some cases, special monsters created especially for these events will show up on certain maps, often carrying valuable items. The events that take place depend entirely on the administrators and Game Masters of a server.
