Metacreativity powers create objects, creatures, or some form of matter. Creatures you create usually, but not always, obey your commands.
A metacreativity power draws raw ectoplasm from the Astral Plane to create an object or creature in the place the psionic character designates (subject to the limits noted above). Objects created in this fashion are as solid and durable as normal objects, despite their originally diaphanous substance. Psionic creatures created with metacreativity powers are considered constructs, not outsiders.
A creature or object brought into being cannot appear inside another creature or object, nor can it appear floating in an empty space. It must arrive in an open location on a surface capable of supporting it. The creature or object must appear within the power’s range, but it does not have to remain within the range.
For the purpose of psionics–magic transparency, metacreativity powers are equivalent to powers of the conjuration school (thus, creatures immune to conjuration spells are also immune to metacreativity powers).
