My players are gonna end up in the country’s capital soon, and I have maybe half of it prepared. So, I’ve built a few factions of my own, so I’ll drop some of those ideas in here, but first, here’s some resources:

Some Reddit Threads -
“Interesting/cool names & concepts for mercenary companies?”
“Interesting Guilds/Factions in Homebrew Worlds”
“ [5e] Could there be a faction of "good" fiends?”
Alright, and as promised, here’s some of the faction’s I’ve built! (Most of them are some altered version of something from the 100 Factions list.)
Order of the Lynx - Right hand men to any nobles or royalty, will find them drugs, women, or illegal goods. Will also bury any bodies without question or hide bastard children. They work primarily as an underground network of coded messages and silent nods.
The Sirens - Most brothels have at least one member of the Sirens within their ranks. A Siren’s duty is to obtain secrets to blackmail corrupt leaders and protect others in good standing. A few are assassins who work primarily with poisons or mind tricks that will cause insanity. They all report to Madame Eloise Song, a Yuan-Ti pureblood who is highly respected and feared in the community. She runs a brothel called The Songbird, which is the main location of The Sirens. They are a force of good, wanting to keep balance and peace in the world.
The Hillroses - Traveling family of gnomes seeking to make peace between all races and countries. There are many groups of them, but most have gotten separated and are usually always looking for each other. They’re fairly peaceful but will resort to bribes and lies where necessary to gain passage or buy shiny goods off weary, gullible travelers.
League of Lopt - An underground goods network dealing primarily in illegal trading. They trade in poisons and secrets. Their negotiations start with offering you a drink and end when they decide to give you the antidote. They are led by Dai Li Ba, an ancient Tortle who is looking to pass on his mantle and has yet to find an appropriate apprentice. They keep members in bars around town, seeking those wanting to make a trade or a deal.
The Court of Owls - Assassins for hire. They tend to run underground fighting rings for money in towns where violence is not prohibited. Their methods are infiltration over time and dealing a killing blow. However, they can also strike fast, but the team that does that costs more and is referred to as Screech Strike. For blackmail materials and intricate spying without a kill, one would want to hire a Scops Servant. (Every group within the Court of Owls has some owl-associated name because why not?)
This list is for my Drevail Campaign and may expand in the future.
