Origin Story of the Clans

This is the story of how the clans were created. The events that happen likely aren't exactly what happened, it's just a myth that's passed down.
Hundreds, maybe thousands of years ago, the mountain of fire--now known as a volcano--erupted. It caused mass death and starvation all around it, and for months and years life struggled to grow back. However, many months after the eruption, a few animals managed to make a living here. The first felines fought constantly for food and territory, with each other and with other animals. 
One day, twelve cats (each named a zodiac sign) came together, hoping for peace. They meet at the volcano. It is a full moon, but it's impossible to know this due to the dark ash and clouds clogging the sky. A strange light is glowing from inside one of the old lava tunnels, and they all go in. It's dark and cramped inside, smelling of ash, but they keep going towards the center. 
The reach the center of the volcano. A lava waterfall is flowing in the middle, and they turn to leave. A sudden earthquake shakes the ground, and they're unable to move. A blinding light fills the cavern. Suddenly, the earthquake stops, and they look up. The lava has turned to water, and a massive cat is in the center--a smilodon. She says her name is Destiny, and she has come to guide them.
The twelve cats split into groups of two, based on what their talents are, and go to find more cats to join their newfound "clans." Destiny goes back into the waterfall. When they leave the volcano, the ash has cleared and the stars are shining--the spirits of all the cast lost in the explosion.
Each pair finds others that look and live similar to them and create six clans. In the beginning, the two are co-leaders, but many generations later one of the two becomes the deputy. Since the ash clears away, plants start to grow and prey returns. The lands become fertile again, though the cats still remain in clans, hoping a disaster never strikes again.
Six original clans: IceClan (tigers+lynxes), BoulderClan (saber-toothed tigers+mountain lions), JungleClan (jaguars+margays), SwampClan (clouded leopards+fishing cats), SavannahClan (caracals+cheetahs) and DesertClan (lions+leopards)
