The Way, also known as psionics, is a dominent practice in Athas and has come about as a natural survival trait among the majority of denizens in the Tyr Region.
It is the ability to read minds, move things without touching, balance on the shifting sands or even create small kinetic flames.
The Noble Houses place great value in these abilities and schools in each city exist to hone those skills (and give a basic education). As such, being particularly adept in the way is a status symbol amongst nobility.
While The Way is completely separate from magic, Way adepts are often trained into Templars for their ability to formulate their mind and manipulate their surroundings is strong.
