It seems that for now the Acterians would be set aside. Their mental wounds allowed to be healed, and their mental fortitude to grow. Lu was content with the actions of Acter, trusting that eventually the mortals would see the light.
Lu learned several things from The First Men, and decided upon creating mortals himself. The world was filled with such beauty and bounty, a fact that the Acterians had completely missed out on. Foolish mortals, they wrought their minds upon the mighty symbols of gods and forgot to view the minor ones. They had forgotten the feeling of sun on their backs, and the smell of the forests after it rains. They had missed the blueness of the sky and wonder of the stars. They had never tasted the sweet fruit of the trees, and the refreshing clean water of a mountain stream. Instead these mortals knew only the dark hard walls of tiny caves, of sour lichen, and only of pain.
Lu's mortals would be different. Lu took the many plants of the forests and wound them together until they combine into a singular mortal. Lu does this over and over again, weaving, integrating, growing, until he has a race of plant people. They are larger than the Acterians, most of the plantmen standing over ten feet tall. The plant people, which Lu decides to name the Phopu, are almost entirely photosynthetic. Their skin contains a great deal of chloroplasts for the creation of energy, as does their hair. Their eyes have a dim glow, a very very weak version of the sun eagle's sight, which is characteristic of Lu's creations. Each Phopu is slightly different, depending on which plants they were composed of. This leads to certain genetic traits in the population. Some have thorns, others have pine needle (as opposed to leaf) hair, some are poisonous, etc ect. All of them reproduce in the same manner as flowers, but their ability to move eliminates the use of pollinators and allows for a more manual approach. To survive the Phopu only need light, water, and some nutrients (extracted through extendable roots in their feet), though they do have a digestive system allowing them to supplement their diet with fruits, nuts, and berries.
Lu tries to make their lives easy, allowing them to thrive on only what Lu provided for the Acterians. Light, water, and air. He makes their plant minds resilient to the cosmic energies that were aimed at the meaty minds of mortal Acterians, giving them an innate knowledge that the light comes from their god and that darkness is synonymous with starvation. (Hopefully those two mental manipulations will keep them from approaching the mentally radioactive temple and obelisk).
Lu creates the Phopu: a race of photosynthetic plant people. They are bigger than humans, and can subsist almost entirely off of light. Their minds are wired so as to be resilient to mental energies.
