Ludibrium Castle
- Region: Ludus Lake
- Roads: Ludibrium Castle, Ludibrium, Ludibrium Town, Hidden Street, Lowest Floor of Clocktower
Ludibrium Castle, commonly referred to as "Legoland", since the town is made out of Lego-type blocks, is a floating town that is supported by two monstrous 100 floor towers: Eos and Helios. It is suspended over Ludus Lake between two islands, where Omega Sector and Korean Folk Town are located. It is somewhat isolated from the rest of Ossyria island, though a trip underwater can get the player back. Ludibrium Castle is accessed via a train-like ship at Orbis. It is also accessible from Korean Folk Town via its link to Aqua Road. The monsters here are mostly toy-themed and time-themed. According to quests related to the Fourth job advancement, time has stopped in Ludibrium due to the crack in the dimension near the Time Sphere, which has allowed monsters like Alishar and Papulatus to sneak in to the Maple World.
- In JapanMS and GlobalMS, there is a special Party Quest for characters between the levels of 51 and 70, called the Ludibrium Maze Party Quest. It involves navigating a maze and collecting as many passes as possible for experience. There is no boss monster, but there are a few special Tauromacis from Sleepywood's Ant Tunnel that drop large numbers of passes. It is accessed in the main town on the exterior of the clock tower.
 Toy Factory
- Level Range: 30-59
The entrance to the Toy Factory is located in the middle of Ludibrium Castle. The Toy Factory is very confusing, as it has many maps linking to each other. Before reaching Clock Tower Dungeon, a player must pass by here. At both far ends of the area, there are important NPCs located. The maps branch out in long paths from the center, with each level getting progressively shorter, forming a bowl.

 Clock Tower Dungeon
- Level Range: 61-108
Clock Tower Dungeon has the strongest monsters in most versions of the game, with the exceptions of Aqua Dungeon and Leafre. At the "Path of Time" map, there is an extremely long ladder. At the bottom, one can go two ways: to the right are monsters such as Soul Teddies, Death Teddies, Klocks, and Phantom Watches. After the Grim Phantom Watches, Thanatos, a level 108 monster, may be found. The monsters on the right are all undead. On the left, players may find monsters such as Buffies, Buffoons, Ghost Pirates, and Spirit Vikings. In the map past the Spirit Vikings, another level 108 monster, the Gatekeeper, is located. The monsters on the left side, unlike the right, are not weak to heal. Once past Thanatos and Gatekeepers, there is a map devoid of any monsters. This is the bottom of the clock tower, where players are able to access Papulatus, one of the "Big Four" boss monsters.

 The Ludibrium Towers
- Region: Ludus Lake
- Roads: Eos Tower, Helios Tower & Hidden Street
 Eos Tower
- Level Range: 23-47
Eos Tower is one of two supports that keeps Ludibrium Castle afloat. Eos tower has 101 floors (its 101st floor being the area for the Ludibrium Party Quest. This Party Quest is for players who are level 20 and above.
Upon entrance to the Eos tower, a player can accept the Dollhouse quest, which allows only one player on that specific channel to do the quest, similar to how a party quest functions. Players have a time-limit of 10 minutes to find the 'special' dollhouse out of 10 similar-looking dollhouses.
Return-to-nearest-town scrolls originally did not function inside the tower, but recent updates have allowed them to be usable. Using a return-to-nearest-town scroll on floors 67 and above will return you to Ludibrium, and using it on floors 66 and below will return you to Omega Sector. Also, Eos Rock Scrolls can be used for rapid transportation within the tower. By doing the "The Lost Guard" quest (which can be done daily), from the Lost Soldier NPC, which can be found on the 94th floor, a player can obtain 20 Eos Rock Scrolls. There is also another quest that gives 20 Eos Rock Scrolls, enabling a player to obtain up to 40 Eos Rock Scrolls per day at both ends of the Eos tower. On the lowest floor, the first floor, players may access Omega Sector.

 Helios Tower
- Level Range: 36
Helios tower is located in the east end of Ludibrium Castle, mirroring the Eos Tower; it is the other support that keeps Ludibrium Castle afloat. The only monster is Retz, a hamster-looking monster resembling the Black Ratz in Eos Tower. Only four floors are accessible in this 100 floor tower. Fortunately for travelers, an elevator takes them from the 99th floor to the 2nd floor. The 1st floor holds a library where a giant magical book can be found, which can take players to Korean Folk Town. In some versions, the Ludibrium Time Control room has been implemented, where players can take a trip back in time to Ellin Forest, Victoria Island's past.
