Ok, here i go:
BackgroundThe Peskitoriantais are desendents of the Toriantais. The Toriantais were much more cavemen like and walked on all 4 legs and also had the full tail. Because the Toriantais were so much closer to the stage of just comming from the water, they still had their gills, but also had fully functional lungs. They have learned to use their backbone more and walk on 2 legs now to reach up to the top of the trees.
Toriantais:
Before the DisasterOn the planet of Nairot, everyone got along. There were many trades between the few types of creatures living there: Torianstais, Sia, Optrera, Aecivo, and Ruean. There was an obundance of plants, and all 5 species were evloving and advancing themselves into the Space Age. Enough land for all the roam free and talk and play how every they feel. Water was plentiful and the air was clean and fresh.
The Optrera found a new planet close by that they wanted to colonize for themselves because they knew something bad was going to happen to their planet.
Out of all the creatures, the Ruean were the smartest of them all. They already had a spaceship and was getting ready to take off and leave, until with their superpowered telescope, saw a meteor shower heading straight for their home planet of Nairot. So they must act quickly.
The head of all the major cities got together to think of a plan, and it was to evacuate the entire planet. Now even a not so smart species could figure out that the amount of time they have to get everyone off was impossible, and the only ones with a spaceship were the Ruean.
So the Ruean decided to leave the other species behind. And the Sia were not happy at all, The Sia attacked the Ruean city will there was nothing left but the Spaceship. The Sia got a little paranoid and took the ship just to leave the Torianstais, Optrera, Aecivo and the left over Ruean.
It was only a couple of hours till the whole planet would be destroyed, until an idea popped in the Toriantais head, we have gills, lets use them.
So they did their roar all around the planet for all Toriantais to head to the water, and stay there. To the other species, they had nothing of use to avoid this tragic event. So the day came, and BOOOMMMM!
The DisasterMeteors from all around crashed into the planet, leaving it firey and smokes clogged the lungs of any thing living up on the surface. The Toriantais swam further down and down into the water to avoid the heat. Splashed were continously hitting the waves at the top. The crash only lasted for about a few minutes, but the damage would last a lifetime.
It has been a couple of weeks after the event and no more food has survived for them to eat. The only thing left were little fish, and yet they never have ate anything but plants. So now was the time to go a little carnivore. They have found that there was no use of the tails, so everyone decided to eat their own tail just to hold them over a couple more days until they head back to the surface.
All the tails were gone on every Toriantais. They swam to the surface and once on to the dirty sand, they looked and saw a whole new planet, it was unrealistic. New trees had formed, new terrain and new grass. It is like nothing was there, until they saw a little Sia feasting on a dead carcass. The Toriantais met it with questions and friendliness. But the Sia didnt, and it immediatly jumped onto the neck of a Toriantais and started biting and chewing it. All the other Toriantais had were their teeth, so they tried to grab it with its teeth, but no use until one of them stood on the back 2 legs and punched the Sia with its front 2 legs and then went back down on four. The Sia was stunned on the ground for a few seconds and then ran away.
The Toriantais liked this new way of attacking and started trying to walk on the back 2 legs until they all could do it permanently. The Toriantais have learned a new trait of annoyance and aggretion now to other animals, so they added Peski infront of their name, though it is pronounced Pesk-eh, not Pesk-E. The now new species of Peskitoriantais started building again and multiplying themselves. Since there was no other animals on the planet except themselves, they went back to being herbivores and ate plants.
Post DisasterWith the newer technology going on in the city then any other time of their lives, they thought they were living great, until some unexpected Sia arrived to greet them
Sia:

There was about 50 of them at the city gate. Some of the Peskitoriantais went to see what they want, but they went with speculation. They walked outside the city gates, and what is when the Sia started attacking and they kept on comming from back beyond the hills. They continuesly attacked and attacked. The Peskitoriantais were wondering how this was because no other lifeforms were here. Until they saw it, a huge UFO landing beyond the hills, and then leaving, then comming back. It was unloading and loading Sia to attack us.
Thats when the Peskitoriantais started to use their lasers and destroy the spaceship. The Sia attacks soon died down, and it was temporarily over.
The Peskitoriantais then soon found that planet that the Optrera also found, and the ones who now colonize it is the Sia, and it looks like they are doing very well.
The war still continues, and will always continue until the Spore game is released. Whose side are you on, and will you help them?
Ill post the culture things later
