World of Sharr
If you ask another Wyser, he will tell you that Forcers are masters of the basic principles of manna use. If you ask a Forcer, he will tell you that he is a master of magic. Where others sense, they see. Where others move, they push. Where others need help, they stand alone. This is the philosophy through which Forcers see themselves in relation to the other disciplines.
Through intensive training, a Forcer learns to glean information from its surrounding that other Wysers would not be able to pick up on. This could be simply telling what the exact source of another magic-user’s power (an elemental, spirit, demon, seals, etc.), or seeing through well-made illusions. Forcers have also found a way to uleash pure manna into the world at large without using any medium. Forcers are known for combatting oppenents with telekinetic powers or even with manna itself, often causing severe burns.
