The Beginning
Since the day when dinosaurs roamed, there was a new fledgling species. They were the Razog. Back then they were simple creatures, but evolved rapidly. They clocked in at around 6 feet, and weighed a miniscule 200 lbs, a lot like modern-day humans. What isn't like humans today were their reptilian features and their genius intellect at a young age. Their great prophets sensed something wrong, but could do nothing about it at the time. They sensed a danger like no other, the meteor that would eradicate all living things in the world.
By the time when the meteor hit, they had evolved enough to do something about it. They took what evolutionary traits they had and went underground. They built strong archways overhead to make sure nothing would crumble under the pressure. They had enough supplies to last Millennia, and they had Tetris. Yes, the Razog had invented a game that as addicting as crack. They would not get bored.
When they arose from their apocalyptic hideaway, everything was destroyed. The once lush and green surrounding was nothing but barren wasteland. Few trees stood and were there were very little signs of life, but there was some.
The Razog took it upon themselves to cultivate this planet. They would help make it grow and flourish to its original status. While doing this, things around them evolved. It changed so fast with the help of the Razog. The Razog too were changing. They were evolving at an incredible rate. Their features changed. The scales were soon falling off, the tail getting shorter every decade, the face changing.
The apes too were evolving, little by little. Soon, the Razog and humans became nearly identical, save for one thing. The Razog somehow developed powers. With these powers, the humans revered them as Gods. The Razog taught them how to build, how to hunt, how to forage, how to plant crops. They helped the humans live and for that they were grateful.
But soon the humans feared them. If but one were to turn on them, they would perish. They planned for nigh a century and finally got their chance, in the form of a total solar eclipse in their region. The Razog depend on the sun for their powers and without it, even for a couple minutes, they're powerless.
The humans swept in and killed all who opposed. Many fled but few escaped. The ones who did escape went into hiding together. They would try later to blend in with the humans, for they now know they cannot live without them now.
