Energy Costs

five points of order energy ==Process to Actualize Form visualize a hollow sphere indented so as to receive <target>

This form builds on the resonance of the form Mirage: it allows one to send inanimate objects along the lines of resonance that one has with one's Exoma microcosm, storing them there until retrieved, either by visiting one's cosm or with the form Convexity. There is a base cost in order energy associated with this operation, and an additional cost per item sent that goes up with one's planar distance from the Exoma, and down with one's facility with this form.
