Lyoko
Lyoko is a virtual world in the French animated television series Code: Lyoko. It's divided into five seperate sectors, all with their own unique features. The first four sectors are arranged around the fifth, like the spokes of a bicycle wheel. Each sector is isolated from the others by the digital sea. There are 10 towers in the four main regions; 9 neutral towers and 1 passage tower. The fifth sector, otherwise known as Carthage, has one confirmed tower. There may be more.
Ice Barrier (Sector 1)
Composed of large glaciers and thin paths around the edge, the Ice Barrier is just as slippery as ice in the real world. The towers are very well hidden here, and are often only accessible through tunnels one must "surf" down. In the tunnels, stalactites and stalagmites pose a serious threat at higher speeds. On occasion, they have to go through a maze to find the tunnels.
Simulated water exists in this sector, and like actual water can be swum through.
Forest (Sector 2)
Mystery reigns in this enchanted-looking forest. Graceful trees, suspended in mid-air, let their roots dangle into the void. The Forest sector can be considered the most beautiful. It also has paths rather than plateaus, though the chance of falling into the void is less than in the desert. The trees also provide excellent cover, which can lead to traps.
Desert (Sector 3)
Just like any desert worth its name, this one is dry, yellow and sandy, as far as the eye can see. Even the oasis, dotted about the place, do not have much greenery. Our heroes particularly have to take care not to run into any of its needle-like rocks. The biggest danger is falling off the edge (plateaus are rather small here) and into the void.
Mountain (Sector 4)
Its peaks craggy and its stones sharp, one false move and the heroes topple off the rocks into the gaping void beneath. The Mountain sector is full of moving platforms and tricky obstacles, and is known for having further platforms underneath the "cloud cover" obscuring the digital void in areas. These clouds make it difficult to aim oneself onto the lower plateaus; and even if you land properly, twenty life points are lost on impact.
Carthage (Sector 5)
A sector hidden deep within the heart of Lyoko, it is only accessible by the special password SCIPIO. This summons a Transport Orb to the edges of the other sectors furthest from Carthage to carry our heroes to the sectors core. The sector itself is shaped as a giant orb with four data streams feeding from it to the four other sectors. Everything in Carthage is blue and geometrically shaped. The interior of the orb is an ever-changing maze, designed to act as a security feature to prevent intruders from finding their way. Once accessing Carthage, a three-minute countdown begins, letting the users try to travel the labyrinth and disable the security system. Failure to deactivate the security device results in the user being trapped in Sector 5 and having to wait on someone else to reset the maze from the entrance hall. After exiting the maze, one must try to jump onto an all-directional elevator platform bearing two Eyes; once you are on, it will travel straight to another platform in Carthage's outer spaces where there is an interface.
Carthage has also been revealed to be XANA's own sector, where he essentially exists. Full access to the "super calculator" and Lyoko can be had at the interface on the final platform. While Lyoko is being controlled from Carthage, the user controls in the lab are locked out. This territory is not connected to the regular materialization program, which means that if the characters lose their life points there, they will not automatically return to Earth unless the proper program is run.
This place also seems to be XANA's monster-building unit. It has been discovered that there are hidden towers inside Carthage where XANA can activate them without fear of Jeremy's super scan detecting it.
- The password SCIPIO comes from Scipio Africanus, who defeated Hannibal of Carthage in 202 B.C.
Digital Void / Sea
The void that surrounds the territories of Lyoko is something of a death trap - once you fall in, the only way out is to use Jeremie's devirtualization program. Digital beings from Lyoko, including Aelita and the monsters, would be destroyed if they fell into the digital void. The sea waves and moves like any water in the real world.
