Okay, there is some preliminary information for you to be able to answer this question: There is a sword of great power, a McGuffin, and a destined one who wields it. The destined one has two companions. These three we'll call Gang 1, for simplicity.
Then you have the King's Guard, who want to retrieve the sword (it was stolen from the treasury). But also, the leader of the King's Guard wants revenge on one of the members in Gang 1. We'll call these people Gang 2.
Then there is this crime boss, who also wants the sword, for power. Him and his men we'll call Gang 3. He also has a bit of a grudge to someone in Gang 1.
Then we have another crime boss, though he is of a prominent crime family, and he sends his sons on this mission. This is Gang 4, and he is in a feud with Gang 3. Also, one of his sons are one of the destined one's companions. So, his sons want to not only take the sword, for power, but they also want to retrieve the son in Gang 1.
Then you have the destroyer, who has hired a crew, so he can destroy the sword, both due to conviction but also personal motives. He and his crew is Gang 5.
Within Gang 5 is someone who is a bit more educated, and therefore knows the power of the sword, and therefore decides he doesn't want it destroyed, but rather in his hands. So, he stages a mutiny within Gang 5, which will be Gang 6. He also has personal motives involved in this, as he wants to fill his fathers shoes of being a captain (this all happens at sea, like a big ship battle, boarding, fighting, etc.)
Then you have the captain of the boat Gang 1 is travelling with. He sails for a travelling company taking people from one dock to an island, and then further from that island to two different countries. But he takes his job very seriously. His motto is "I always get my passengers to their destination". He and his crew is kind of Gang 1, but also kind of another gang, Gang 7. Whatever, it is for you to decide.
Then you have the knight, who is wanted and has been through hell. He knows the destined one, and is kind of a failed mentor to him. He was supposed to guide him on his quest, but they were separated. Now he is coming back to help him. Despite being one man, we will refer to him as Gang 8.
Then you have the renowned, super-skilled bounty hunter, who is coming to retrieve the wanted Knight, or Gang 8. We will refer to him as Gang 9.
And finally, we have a powerful being who guards the mortal realm. There is a threat to the mortal realm, an invading God, which is why Gang 1 stole the sword to begin with. But the destined one within Gang 1 is merely a child, and the powerful being believes the sword is better in his hands, as he is a more capable fighter. We will refer to him as Gang 10.
And that's everyone. I am a big fan of Lock stock and two smoking barrels, and the way those kinds of narratives play out, when all the subplots, with all their unrelated characters, meet in a messy, complex confrontation. But I'm wondering, can this kind of stuff be too complex? Too complicated? Too disorienting?
Just so it is clear, all these characters have had sufficient time to have their stories told and their motives made clear.
