These heroes are all Psions, followers of a strange and mysterious form of power. Psions shun the world to turn their eyes inward, mastering the full potential of their minds and exploring their psyches before turning to face the world. Psions are incredibly rare, and most prefer to keep the nature of their abilities secret. Using their inner, psychic strength, they can read minds, fade into invisibility, coordinate their allies, and seize control of the physical world and bend it to their will.
Psions are loners. Most discover the secrets of their power through vague references in tomes of lore or by ingratiating themselves to a master of the power.
To master their power, psions must first master themselves. They spend months and years in quiet contemplation, exploring their minds and leaving nothing uncovered. During this time, they shun society and typically live as hermits at the edge of society. A psion who studied under a master will have travelled to one of the schools led by a psionic order teaching their students in a specific methodology and philosophy of how to use their abilities.
When psions finally master their power, they return to the world to broaden their horizons and practise their craft. Some psions prefer to remain isolated, maybe becoming a teacher to other students, but those who become adventurers aren’t content to remain on the fringe of the world.
