The Sewer.

The Sewer is a sewer in Boulogne-Billancourt, and is the route that connects Kadic and the Hermitage to the Factory. It is used by the Lyoko Warriors to get there and back. The Sewer itself has strips of a walkway on both sides, on which our heroes transport themselves. There is water in the middle. Yumi, Odd, and Ulrich use skateboards to traverse the Sewer, while Jeremie and Aelita use scooters. The Sewer empties into the Seine, and is probably not used for waste products, meaning that it's probably a storm sewer.

Known access points

  • Behind an infrequently accessed door in one of Kadic's buildings. Infrequently used after season 1.
  • The manhole in the woods.
  • Two access points next to the bridge leading to the Factory.
  • A little-known side door at the Hermitage.
