Mo'anwn isn't tall, not quite reaching average height. Except for a band across where his eyes peer from the shadows of his hooded cloak, his face is masked as if he's a cowboy trying to keep out the dust. The cloak flows to the ground, almost completely surrounding him. The black fabric seems to be in constant movement, with no regard for wind or other environmental concerns. His appearance seems designed to ask you not to notice the man inside the clothes, and notice only the cloak, almost as if the man is wearing vestments with a meaning lost to those newly seeing them.


It began with the trees. No living creature on the planet had lived as long, or sensed as much. Far across the sea, the big-headed, gray-skinned bipeds built their city. The bipeds mastered the secrets of the universe, and realized it was doomed. Crossing realities they sunk anchors to hold their city in place. Long before any Kang attempted to stabilize a 'Sacred Timeline', the bipeds sought to anchor them all. Kang's agents, leaping beyond the beginning of his own timeline, came to the city.
The bipeds had no need for such interference. Kang's agents were stripped of anything that would allow them to return from whence they came, and dropped in the forest.
The trees saw. The humans were disoriented, angry, and slightly dangerous. Simple probing provided the trees with an explanation. The humans continued screaming, roaring, shouting, crying as their ears bled. A great cataclysm raged in the tops of the trees. Wind roaring around and through branches strong enough to reach one hundred stories into the sky created a sound no human voice could penetrate, no human ear could resist. So, the trees decided to help. The noise of the wind diminished, and all the humans understood this was the will of the trees. Trees that taught the humans not to need ears. Trees that made the voice obsolete. Trees that would lead the humans to survive.
Time passed. The gray bipeds built a great city, anchored to reality itself, unable to be affected by any hazards the universe would throw at it. Now, they sought to protect the city from time itself. Mystic crystals, built not from matter, but with energies flowing between the quarks and forming the basis for up, down, charm, strange, top and bottom. Energies entangled with every alternate time line that had existed, and all time lines to come. As the crystal grew, more of Kang's agents arrived.
They were strong, and fast, and able to affect the universe in divers ways. They were no match for the gray bipeds. Stripped of their ability to return to their own time, these, too, were dropped in the forest.
The humans that met them did not remember Kang. They had their own creation myth, their faith, their trees. Trees that had developed a symbiotic relationship with the humans. Their minds were linked to the trees, the trees provided the humans with all that was needed to live in the environment, the humans provided the trees with opposable thumbs. Kang's new agents sought to establish a beachhead, and were slapped down with no more effort than it takes to whack a puppy's nose with a newspaper. The trees explained, and Kang's agents accepted their exile, mostly.
Several of these agents were able to shield their true minds from the trees. They joined in with their fellows, and plotted secretly to take power for Kang. The years passed, the two human factions grew, only one faction realizing it wasn't alone. Generations later, Kang was forgotten. Whether or not he sent another expedition is unknown. It mattered little. The crystal was complete, the city shrunk to one-thousandth of its original size, in perfect stability.
Mo'anwn was an arbiter. An agent of the trees, guiding the rest of humanity into the paths of truth. The trees gave the arbiters their power, training them and even providing portions of their millenia old minds to each arbiter. No power could stand against them. The trees told them all when the gray bipeds became suddenly silent. Something of that nature might require action from the trees, themselves. They sent Mo'anwn to ask the bipeds if they needed assistance. The trees knew they wouldn't answer, but Mo'anwn would show them they weren't alone.
It's a long way across the planet, especially for one man to traverse alone, but Mo'anwn made it. Along the way, other denizens of the world he'd never before seen were making the same trip. The four-legged white runner that zig-zagged across the plains, his attitude suggesting he already knew he was too late. The sedentary philosopher, all limbs and no movement, fatalistically explaining that it had never been up to him. The grinning predators, not there and then there, savagely attempting to damage his mind before they attempted to consume his body. It was all wondrous to Mo'anwn.
As he reached the gray bipeds city-in-a-crystal, his last thought before he reached out to the inhabitants, was "I wish I could see more". Even as the pinkish glow washed over him, and sent him hurtling through space and time, Mo'anwn could see the crystal begin to crack.
Then he was falling. Through space, out of time, plummeting to a blue and green planet that seemed as unfamiliar to him as the moon he passed by. The rush of wind as the atmosphere thickened reminded him of the trees at home. He reached for their comforting touch, and it wasn't there. That could come later, his cloak unfurled into an airfoil, and his descent became more horizontal than vertical. Slowly, he spiraled down, opening his mind to get as much information as he could. The people's thoughts almost overwhelmed him. By the time his mind was clear again, he was landing. There was an altercation between two of the humans, he stepped in and the bullets that were fired bounced straight back into the shooter. Fortunately, the survivor was one of the city's organized protectors, She helped him sign on with the department as a consultant, and as both rose through the ranks they became closer.
Then, one day, they came for him. Their records listed him as a variant originating on the world, he didn't bother correcting them, and surrendered to them as soon as they made clear who they were.
