By the way, I am enjoying the psionic flavor where:
• The mind is nonmagical
• The magical Weave is psychosensitive
The Weave itself is an "interface" between "raw magic" and spellcasters. It is impossible to access raw magic accept by means of this interface. The spellcaster "plucks" (manipulates) the Weave to create a magical effect.
Psionics appears to engage the Weave directly by means of thoughts, possibly by using words and chanting to articulate and focus their thoughts. In this way, the nonmagical mind creates magical effects.
Psionics can appear on both sides of the "common" arcane-versus-divine generalization. The Bard and the immortals access the Weave directly by means of words to create reality magically. The Paladin oath is a kind of sanctification of the will of the mind.
I view Psionics and Primal to be the same thing. Psionics is the most ancient and primordial form magic, where a mind manipulates the weave directly. The only difference is, Psionics focuses on humanoid minds, while Primal also includes the minds of rocks and trees. Rocks and trees have nonhumanoid minds, but they still have a kind of mind.
I view the Wizard as a kind of technology that manipulates the Weave that is inherent within objects and other spell components. So manipulating the components channels the directions that the Weave flows. The Sorcerer manipulates the Weave inherent within ones own magically infused body and blood. The Aberrant Mind is a body with an aberrant heritage. Warlocks and Clerics often partner up with other beings who have mastered the Weave.
