The idea came into my head recently. For those of you who know the RPG for phones (sounds lame, I know, but stay with me here), Brave Frontier has a lot of lore in it as a series.
For those of you unaware, it's an RPG set in a basic fantasy world with an anime art style. You play as a summoner who is called upon to defeat the four fallen Gods that hold control over multiple realms that you travel through.
The lore goes that there was once an ancient war between humans and gods when the humans decided to rebel. Many were forced to train relentlessly, gaining magical powers, and people from all walks of life were banding together to combat the tyranny of the gods. Some even ascended to godlike power themselves in their efforts, and are spoken of even into the present day in legend.
Now, those chosen to slay the four fallen gods in the present day are not fighters themselves. Or at least, not the player (since Karl and Seria are obviously very capable on their own... you guys know what I mean. >.>).
The player is known as a summoner, of which there are many in the present day. Instead of fighting directly, they rely on summoning these long-dead heroes to use in battle. Typically a summoner starts with using said hero at their lowest point before they were famous. For an amateur summoner to use a renowned hero is unheard of, as they don't commonly have enough power to muster up anything more than the basics; they must develop and train to summon more powerful units. Units summoned replicate the original's personality, appearance and abilities to a fine accuracy, but are not the original brought back from the dead. Many summoners make use of the same heroes, even multiple in their own squad of summoned units.
So, basically, this RP would be focused on the journey of newly recruited summoners that venture through the continents and worlds to defeat the evil gods. I'll explain in detail how it works if there's enough interest.
