Factions represent the different teams in the server. There are currently three factions, with each their own pages to explain them more in-depth:
A player's faction decides who they activate towers for, who their enemies are and where they will appear when joining the server. All players start off as part of the Lyoko Faction and therefore will spawn at Kadic.
It is possible to become a temporary ally of a faction by being Possessed by a Tower or the Scyphozoa. A temporary ally will fight for their master while keeping their usual abilities (e.g a temporarily xanafied Lyoko Faction player can still summon Overvehicles) but can be turned back to normal.
If a warrior joins a faction other than the Lyoko Faction, they will become a Lyokowarrior once again after 2 realtime days. Other ways to switch factions may vary.
Factions have one-sided relationships and can be friendly, neutral or hostile towards another faction:
