Process to Actualize Form

visualize an articulated spiral

This form has the strange result of providing one with a magickal, prehensile tail. It is thought to be related to the spider monkeys that inhabit the forests of Hanoma, but this is speculative, as the actualization procedure for the form is figural and not biological in nature. The basis for the form is a spiral; the form itself is a symbolic blend of a number of concepts -- grasping, jointedness, control, and intelligibility -- all related to different senses of the term "articulation". The tail serves as a highly adept manipulator, as a respectable light source, and as a well of expressive energy. It will drain one's reserves of order energy so long as it is manifest. The manifestation can be released by the same process as it was actualized.
