Reminds me of the "Eon" Clans i used, in an old fic of mine "Eevee Island"
(Part taken directly from my fic, Eevee Island. Faction names I used highlighted bold and italic. Noye this was written way before the 4th generation pokemon, so no glaceon or leafeon star in it[in 2003 actually])
So he went around to each of the 7 factions the eevees and thier evolutions had split up into. The Purebreeds, who were eevee who followed a strict rule of never evolving. Any who evolved were punished by mulutation, exile and sometimes death. They believed in the purity of eevees and saw evolution as the work of the devil.
One Tribe, the only group to accept all eevees and thier evolutions equally, all had the same status as each other and eevees could evolve to whatever form they choosed. They believed in freedom of choice and followed the teachings of Hevmel. They rarely attacked anybody, but were hated by the other factions, so they were almost constantly under attack. Being the biggest and most powerful group of them all, if they wanted to, they could of crushed all the other factions, ending the war. But they were not fuelled with hatred, like the other groups so they had no reason why they needed to attack.
The Mist, a group of eevees and vaporeon, who believed that vaporeon are the superior evolution. All eevees in this group wanted ont thing above all else, the have the glory of evolving into a vaporeon. They believed that because thier island was surrounded by water, that water energy ruled the island, therefore the water pokemon should rule because they harness the power of water. Despite not being great warriors, they proved a force to be reckoned with when attacking from the water or on a rainy day. They were very smart, and planned thier tactics well.
The Inner Flame, flareon and eevee who worshiped fire. They believed that by worshipping fire they would become stronger warriors. They were always training for war, and if they weren't, they were pampering themselves up. They tended to be very vain, cruel and unthinking but extremely honourable and brave.
The Storm, a group of jolteon, eevee and the occasional vaporeon. They believed that the awesome power of thunder was the ruling force in the world. Generally weak warriors, they none of the less proved an exetremely powerful force on the battlefield because they were the most organised force on the island. They were well known for raiding other tribes of eevee evolutions, stealing thier young. The stolen babes were trained to be fanatic vaporeon, which had a critical purpose within the ranks as "rain-bearers" for the jolteon and tough, hardy warriors.
The Overmind, a group of eevees and espeons, who believed that the mind held far more power than the elemential forces of fire, water and electricity. All of them were connected in a psychic link which allowed them to discover things quickly and ambush others. They believe in striving to finetune thier psychic powers and training others in the psychic arts was the road to peace.
The Shadow, a inferior group of eevee and umbreon. Forced by one way or another to flee from thier original homes, they embaced the darkness to survive. They were not evil, just misunderstood, especially by espeon, who saw them as bestial. They proved to be tough warriors on the battlefield and were excellent at sneak attacks, ambushes, scouting and assasination. The shadow consider the pack more important than the individual. Many umbreon died fighting against unwinnable odds to save the pack from being destoryed.
I actually almost got flamed for referring to flareon as vain. :-S
