Chronological: X.A.N.A. Awakens
|Also known as||Sector 1, Polar Region, Ice Barrier,|
|Terrain features||Icy platforms, tunnels|
The Ice Barrier is a sector of Lyoko. It is sometimes referred to as the Polar Region (because it is covered in ice) or Sector 1 (as referred to in Mister Pück and Saint Valentine's Day). It also has virtual weather, as Jeremie pointed out in The Girl of the Dreams and in a way by Odd in Cold War.
The Ice Barrier is made up of two parts. The first part is the surface, composed of glaciers connected by narrow paths and large lakes of icy water. Monsters cannot swim, so the icy waters will destroy them if they fall into it. Most of the Towers are based on the surface. The second part of the sector is below the surface; tunnels connect the two areas. Team Lyoko often has to surf down these tunnels to get to an activated Tower.
The Ice Barrier is home to all kinds of monsters, such as Bloks, Hornets, and Mantas. Due to its difficult range of reachable locations, X.A.N.A. placed his Boulogne-Billiancourt simulation program there in Ghost Channel.
In Sabotage, X.A.N.A. activated a Tower in the Ice Barrier that was too well-guarded for our heroes to reach, and they were running out of time, so Aelita deleted the Ice Barrier at her own will, destroying the activated tower in the process.
In season 1 this sector used to have a strange light source that was always lighting and shadowing Team Lyoko's faces. It is most likely that it is Carthage's shining outer shell, but it is unknown why the light was taken away in season 2.
- This sector was wiped out between seasons 4 and 5 due to data degradation. It's unknown if Jeremy will recreate it.
- This was the only sector Jeremy was ever shown to visit. In season 1's episode "Ghost Channel" Jeremy was virtualized into the artificial enviroment which was inside this sector. It's implied he visited another in season 2, but this wasn't shown.
- This was the first sector Mantas were shown in outside of sector 5.
- This was the first and only sector that Odd and Ulrich believed they were in in Temporary Insanity.
- The Kolossus only appears in this Sector, as well as the Ice Replika
