Hello and thanks for checking this out. So my problem is I really want to start up a Bleach RP, now if you have no interest or even no knowledge of what Bleach is don't worry, this won't be a great wall of text all about Bleach, the paragraph below give a little background but that will mostly be it. No, my question is more about how to structure and format an RP which will be set in the Bleach universe.
So for a smigein of detail, in Bleach there is the Gotei 13 which is, essentially, a small organized army or sorts filled with Shinigami or death gods who act as Spirit Samurai and help the dead to pass on to heaven. If a soul isn't passed on it becomes a monster known as a hollow, and the Hollow are the main antagonists to the Bleach universe in a very vague kind of way. So the RP will need to establish these two sides, the Shinigami who live in a pseudo 'heaven' that basically looks like feudal Japan. Whilst the Hollow who skulk around the living world eating souls and their own plane of existence known as Huerco Mundo (Hollow are all designed Spanish).
Now, traditionally the way Bleach RP's have gone is the Gotei 13 and all it's 13 squads are set out and people make characters for the Captains and the squad members etc etc. Then some make Hollow characters for everyone to fight against etc etc. There are multiple problems with this, at least from my point of view. Firstly, the Gotei 13 is never actually filled, which makes sense since there are probably around 30+ positions that would make an impact as a PC. With 30 people the RP is huge, despite the fact 30 people probably won't be interested, even a group of dedicated players wont make enough characters to fill the roster. So the RP has to be focused, on a smaller group of easily organized characters. However this leads to the next problem, if you have a small group with only a few characters that means you can't interact with the majority of the universe, that being the other Shinigami. They can be NPC's but you would have to make droves and droves of NPC's which would be so tedious.
My basic point is I want to make an RP, set in a universe with a very very large cast. However I want the group of actual players to be small. How can I make this work without limiting the interaction the players can have? I could say the rest of the Shinigami are all NPC, you can control them as you like, but then everyone starts RP'ing with themselves just talking to NPCs. My initial thought would be to BE the enemy, and have a small group who attack the Shinigami, this means you can interact with all of them whilst having a small group that makes sense, however again either they are all NPC's and you RP with yourself when you confront a Shinigami, or one person controls the entire Gotei 13, which is ridiculous because its 30+ people who can all be relevant. We haven't even got onto the Hollow side of things...
How do I control a massive cast of characters with only a few Roleplayers?
**Edit:** I probably didn't explain this very well so any and all questions are welcome if you don't understand anything quite yet.
