With that out of the way, I'll share the ideas and such I have for my future hack.
First off, it follows the story of a guild of assassins. Lyn's tale consists of 10 chapters as this infamous assassin, who is assisted by a guild. The guild is given small tasks for a few missions, consisting of assassinating a criminal that were never convicted, a bandit lord and a few other corrupt people. They are then the mission to assassinate the king of some country, and when they do, their employer (a noble) turns on them and invades their HQ and kills everyone, except their leader and his young son. Pinned down in his own chambers, the main character makes the bold move of signing a fell contract, even though he already had once before. This causes him to go blind with rage, having strength of unmatchable levels. He goes on a rampage and kills every knight inside the fortress. He is snapped out of his rage when he hears his 3-year-old son's voice. He takes his son and leaves him with a local family and then fleas off into the mountains, never to be seen again.
15 years later his son has grown up and is quite the sword fighter. His foster parents never told him about who his real father was and what he did. When he turned 18, his foster parents told him everything. The rumor was that his real father was killed by the noble and his men, (who is now conveniently king.) Because of how oppressive he has been, resistance groups have been forming. His foster family agree that he and his brother should join the rebellion. With those two reasons as his motivation, he sets off to find a resistance group to join, in hopes of some how killing the king one day.
So is this an overall good idea that I should expand more on, or should I just think of something else?
