Although the use of psionics is on the rise, especially among Adventurers, few have the mental fortitude needed to truly master these mind-magics. Among those who take the time to master these powers, few master these powers at the levels that a psion does.
Psions learn all manner of tricks with the powers that they command. They find ways to create illusions in their enemies’ minds, to command and confuse their foes, and to protect their allies by keeping their enemies away. There is a certain amount of rivalry between psions and wizards who feel that psionics are a quick and easy path to power, as well as the very opposite of the external, powerful magics that wizards use. The subtle, more internal powers of a psion are nothing like the flashy, explosive magic of a wizard.
Most psions battle against the power of the Far Realm and its aberrations. Some scholars argue that psionics are the power of the Far Realm itself, but psions rarely ally with those creatures who might most benefit from their aid.
