"any helpful info" is kind of broad. Are you looking for someone to give you information about factions for your presentation? Are you wanting more sources? More factions? I'm just confused about the level of help you want here. I don't want to do your work for you.

Oh, and if you aren't already, add the Sicarii to your list of groups. It's just my opinion but they were always my favorite because of how awesome their story is. :)

It would be helpful if you included any materials you've already looked into.
