"Long has there been the desire to tap into the Throne for use of its powers, of the familiar manifestations of the Heroic Spirits of ages gone by...yet we never expected such power to seek us out instead. Even if it was only for a fraction of a second so immeasurably small, an even smaller line in the sand was drawn dividing us from something...otherworldly. The incarnation of evil itself is at the door, peering in and gnashing its teeth in undulating desire to consume. To Connect. To Shatter as it has always done. Right now, the Holy Grail all Magus have sought after has manifested and sealed itself off in fear of this...beast. We've no means to defend ourselves, save for our final Countermeasure. And so, we plead to the Throne. Beg of it to spare us. And...it listened. A War wages for the Crown of Heroes, and here we have received the ephemeral shards of power that allow mere men and magus alike to stand against the impossible. Here...is where we stand, or we fall." -Director of the Muninn Anti-Servant Foundation, Matias Ansgar
In a world without a ritual to call forth the Christened Cup filled with Humanity's wishes and the blood of the truest saint, a corrupt force from beyond attempts to seize it for itself. To fill it with itself, and to plunge a new world into Staying Night forever with a single wish. Now, its just a matter of humans versus the impossible, with all the power in the world sealed in a bit of magic "cardboard".
So, since that probably didn't tell you anything at all about what this RP would be about, lemme put my pretentious goggles down to actually explain some shit!
To start with, this RP will be set in the setting of the Fate universe, albeit in a world parallel to those who've been established, since canon is finicky and all that. It follows some of the conventions of the Prisma Illya spin off series, featuring the "Class Cards" system, where you'll receive a single card representing the essence of a Heroic Spirit from History, or fiction. There are some stipulations here and there as to what can and cannot be used, but I'll go over those.
Basically, you will be playing the role of a person, either with or without magical experience that recieved a Class Card that fits their personality of the classes: Saber, Lancer, Archer, Rider, Assassin, Caster, Berserker, and Shielder. By possessing that Card, you gain the power to fight against the forces of an unseen evil from another world trying to mess your shit up and ruin everything. With the powers of a hero at your side, there's no way you can lose! Maybe. I dunno, depends on whether you do something dumb or not.
Also, if someone has already claimed a Class Affinity with their starting Card, you may not have a Class Card of that same type to start with. IE: No two Archer Affinity characters, barring NPCs.
