In this RP, the standard Pokémon world is used, but there aren't any humans. Instead, the Pokémon themselves have built the same modern-day cities, technology, and so on themselves. Also, the technological time period is set to be slightly more futuristic, so there's more creative freedom when creating your own weapons, armor, devices, and so on.
In another time, another rendition, there were only Pokémon. Pokémon that built their own modern day cities, a mirror to what modern day humans could create. Skyscrapers, subways, bridges, computers, and even motor vehicles. They adopted human traits and established economies, governments, businesses, and industry. It was as though time and happenstance decided humans simply weren't meant to be in this alternate dimension.
It started with the whispers of a doomsday cult called Xiav, once that prophesized the coming of an age of darkness in the wake of a cataclysm they called Shadow Armageddon. These whispers stated that there would be a dark cleansing of the world, and the only means to survive was to embrace the darkness and become one with it. The leader of Xiav, a malicious, macabre Delphox by the name of Eris, had given the new acolytes and followers of darkness the promise of power and reign over the weak and inferior. In the beginning, some Pokémon dismissed it as being nonsense. But that had not lasted for long...
Rumors became dark propaganda and fanaticism, and the Order of Xiav grew quickly, spreading throughout Kanto and Johto with a fierce, wildfire-like effect. Xiav's acolytes literally turned the land into blighted and cursed lands, blackened, devoid of color and life, and painted the once beautiful lands into macabre zones of grays and browns through the blackest of witchcraft. Only the followers of Xiav could now cross into these poisoned lands, while those that opposed Xiav were inflicted with curses or simply added to the Xiav massacres. Only the strongest survivors were offered the choice of acceptance of submission to Xiav, or were reduced to a bloody heap. With dark and obsessive use of Shadow Magic, advanced weaponry, armor, and equipment, Xiav had quickly become a seemingly unstoppable killing machine of infernal darkness, reducing all those that opposed them into quivering heaps of their former selves, if they were even permitted to live and not become the next blood sacrifice.
The spread of the Order of Xiav had attempted to penetrate into Hoenn and Unova, but here, the reaction was not as receptive as Xiav was anticipating. Instead, they had awoken the Brotherhood of Sonne, a previously underground quasi-religious paramilitary organization with advanced power armor and weaponry, along with signature light and holy based powers and weapons. Under the command of Kaxo the Lopunny, Xiav's presence in both of these regions was quickly eliminated by Sonne. When it was learned that the Brotherhood of Sonne could be the only possible hope of stopping the Order of Xiav, the regional governmental leaders of Hoenn and Unova formed the Holy Council to fund and supply Sonne's campaign effort. All existing military personnel, assets, and intel was bestowed upon Sonne to boost their chances of stopping Xiav.
However, Sonne's limited presence in Kanto and Johto was too little, too late. Before Sonne had any chance to gain a foothold and fortify it in either of these regions, Xiav briskly blew out any candle of hope, leaving the unified regions as a place of darkness known as the Shadowlands. Now, only Xiav rules here, and any former government or inferior civilization had its heart ripped out and replaced with Xiav's darkest of emissaries. All resistance has been tormented and eradicated, leaving the remnants to be forced into Xiav's cloak of darkness and shadows. However, at the same time, Xiav has found it impossible at the current time to even lightly sway anyone in Hoenn or Unova, as both regions have become firmly entrenched in the light and under the Brotherhood of Sonne's adamant grasp.
The war of light and darkness has spread to Sinnoh, Kalos, and Orre. While the fragments of shadow and light have only just begun to step their way into Kalos and Orre as the calm before the storm, Sinnoh has become the fierce battleground that now rocks the world.
The drums of war have sounded, and the war songs of light and shadows now echo throughout the world.
THE ORDER OF XIAV
Under the dark command of the malevolent Eris the Delphox, this clan of warlocks, witches, and sorcerers believes that an inevitable era of darkness will soon come to the world, and that oblivion is at hand. Xiav believes nothing can stop the night, and that they must become one with it and continue to spread and grow in power. Already, the creation of the Shadowlands has been a milestone for the dark cultists, but it is not nearly enough. Xiav will not rest until the entire world becomes swallowed and consumed into shadow and eternal night, and only then will the world will shift from denial to pure acceptance that darkness is life.
Xiav believes that darkness is power, and not only will it allow them and only them to survive in the coming Age of Shadow, but it will also grant them strength, influence, and will allow them to unlock the darkest secrets within the shadows. Already, the strongest and most elite of Xiav's acolytes, warriors, and warlocks wield dark power unlike anything they have ever faced. Many of Xiav's followers use Shadow Magic as a tool and as a weapon, but there are plenty of Xiav's members that have become extremely passionate and obsessed over the dark powers that Shadow Magic has bestowed upon them.
In the meantime, Xiav has created its own infernal military forces, malevolent weaponry, and doom machines of the apocalypse. They have sworn to destroy the Brotherhood of Sonne and anyone else foolish enough to oppose their reign of darkness.
THE BROTHERHOOD OF SONNE
In truth, the Brotherhood of Sonne has existed for generations as a quasi-religious underground force of warriors and scribes set on driving back the forces of darkness. Using the power of holy light and divine blessing, these monks and clerics have driven back and destroyed those that practice darkness and accursed witchcraft. However, because their war was in secret, they found their way into myths, fairytales, and urban legends.
As time marched on, the Brotherhood of Sonne was less about the old ways of fighting with sword and staff, and instead became a paramilitary organization with highly advanced weaponry, armor, and machines of war blessed and powered with holy enchantment. As soon as word of Xiav had arrived, these metallic monks immediately sought out to eliminate it, and unlike other military organizations, Sonne showed a far more promising chance at stopping Xiav.
Now, under the command of Kaxo, the pretentious and resilient Lopunny, Sonne has risen up to a challenge unlike anything they have faced before. To them, the destruction of Xiav would be undoubtedly the proudest moment of their history if they can accomplish it.
MILITARY SIZES AND PARAMETERS
As such, both Xiav and Sonne are highly equipped organizations with a wide variety of advanced military hardware and equipment. Also, all technology compensates for Pokémon of all sizes (think adjustable seats and controls in vehicles and aircraft) and for those that don't have hands, such as a Flareon being able to lie down and operate controls with its front paws, a Pidgeot operating controls with its beak and/or feet, or an Azurill using voice commands (since it doesn't have hands). As for hand-held weapons/firearms, they can either use their hands, or use the weapon from their mouth (kind of like the way Pikachu holds the beam sword in Super Smash Brothers).
Both sides have their own highly-equipped infantry, armored divisions, naval warships and forces, and aircraft, in addition to advanced military technology. If you wish, you can allow your character to be a high-ranking character in the faction you choose. For Xiav, Kanto and Johto will be the prime sources of hardware, weapons, and such, whereas for Sonne, Hoenn and Unova are that source.
In terms of NPCs, both sides have hundreds of thousands of Pokémon backing up their cause. However, the rule of thumb here is that the more there is of a particular unit, the less powerful it is. Thus, the most elite members are very few in number. Also, NPCs that have names, personalities, character development, and important storyline roles are not to be killed in one shot, but can still be killed nonetheless with effort.
In this RP, we're going beyond the official Mega Evolutions, and are putting into effect that any Pokémon already at its maximum stage of evolution can have a Mega Evolution, such as Zangoose, Ninetales, and Raichu. If the Mega Evolution doesn't officially exist, you have the fun of designing it yourself in your character's sign up. Or you can search in DeviantArt and by chance, someone might have already made an unofficial Mega Evolution form for them, such as for Mega Zangoose
, Mega Ninetales
, and Mega Raichu
. But, obviously if it's not official, you don't have to use it, but if you're feeling lazy or are having trouble designing it, searching to see if a fan-made version already exists out there is a good way to go.
To accomplish a Mega Evolution, your character will need a Mega Evolution Stone, which are somewhat common in Kalos, but are significantly rarer in other regions. Finding a Mega Evolution Stone in Kalos should take your character about 3 posts of searching, whereas searching for one outside of Kalos will likely involve a whole side quest and possible NPC bargaining or fighting.
Once your character has the stone, they can turn the Mega Evolution on and off as they please, just so as long as they have the stone. Also, these stones are not species specific. There's no Blastoisinite or Aerodactylite in this, only these general Mega Evolution Stones.
