Alterations in these genes cause changes in patterns of body parts, sometimes causing dramatic effects such as legs growing in place of antennae or an extra set of wings.

Manifestation is an act of trust. It is the soul pouring itself out into its world, like a fisherman casting a net to gather in the fish he seeks with each cast properly made, we will bring what we need to us, but first we must hurl ourselves into the depths without knowing just what lies beneath us.
