I have an idea for my NaNoWriMo this year. It was a work in progress from last year and this year it finally got finished.
Basically we have a group of kids who were stolen from their parents. Meaning their parents and families were killed. These kids were trained as assassins and quickly became the very best.
10 years pass and the kids are all grown up, ranging from ages 18-21. During this time, a new assassin from one of the top guilds is brought to join the group. Some times passes and this new assassin falls in love with one of her victims. She manages to hide that her victim has been kept alive for all this time until the day of The Mission.
The group, which is known as the Cubs, is told to go on a mission. In this mission they discover that this enemy guild, lets call it RF had files for each of them and that this so called mission was a way for them to leave the RG and be killed without suspicion.
Once they learn about their fate, they escape just as the RF's guild blows up and the enemy assassins come to collect their bodies. They catch them escaping and attack them there. That's when two of the members gets hit by poison arrows and just before one dies, she tells them where her lover is, the victim she didnt kill. They manage to track him down and tell him what happened.
The Cubs vow revenge and manage to get themselves to another members hidden bunker. In this bunker, they plan out their whole plan, how they are going to bring down their old guild, let's call it BC. During their time at the bunkers they decide to send 3 of the Cubs to BC to spy on them. There, they get caught and all three of them get tortured to the point where one practically loses his mind, and the other two just rely on each other. One of the two is released with a slow acting poison on her blood. She is sent to give a message to the Cubs, BC doesnt play games.
The messenger arrives, delievers her message and manages to relay the story of their failed stakeout and painfully dies. The remaining Cubs, now 4 at this point, decided to get revenge for their fallen friends and create a plan. In that time, the two tortured members return but only one, the female, survives.
(Theres more to the story but I have only this much time to type that out.)
