The Reach had this circus faction going on and I advertised when the Reach was getting shut down. So, when we were launching, people were looking for different places to play. We were asked if people could bring their characters over to our game, and I said "sure", and so we have the circus. They are currently the largest group on the game. We are looking for characters who don't belong to the circus, so there is more variety to play with.
For example, we have a Common Threads thing (news starting xp) which are RP hooks which reward XP and give you an IC position to be more directly involved in our plots. These include things like story seeds and group membership that so many players find appealing.
For example, we have The Hookup, an entertainment company which is Changeling operated, the extra funding of which is used to develop the city's supernatural network and thereby keep tabs on paranormal happenings.
There's the Fireman/Bastrop Fires hook, which incorporates the real-world wildfire that devastated Bastrop County (just southeast of Austin); in our game world the fires never died, at least in the Hedge (in the real-world side, they are gone), and we encourage you to make characters who know about the Bastrop Fires and have experimented with how to put them out in the past.
Then there is the homebrew Secrets merit, available in chargen. to characters who have history in Austin. Each dot allows a person to know more about Austin's unique history, both mortal and supernatural, such as the NPCs from the past who are pertinent to the metaplot, the location of Hedge gates, and hints and clues as to just what is going on with things like the Moonlight Towers and the stories about the Servant Girl Annihilator. The way this works is by showing you news files you would not otherwise see and by being able to add your Secrets rating to any roll regarding knowing/finding out more about things going on in Austin.
So, we have the Circus. We we also have Austin-centric plots and themes that we'd love people to join in on so we can tell our game's unique stories.
