Hey! It's great to see that this has some interest. I've just got back from a surprise birthday trip away so I apologise for the minor absence.

As for plans, the main idea is to have players explore the accessible parts city on their own primarily. I will write up missions that will initially ask the questions such as: What is the cause of the Black Fog? What is even down inside those chasms? Who is enforcing the No Exit Rule for the Arena?
However, as players, it will be your ideas that progress the mission on. So communication will be a key part of this RP.

There will be some missions with more concrete goals and clear paths on how to achieve them but I hope to have those rather few and far between. These missions will be say...re-opening a blocked off section. Which will then bring all new problems and missions and a new part of the city for you to describe.

Once you have completed a sufficient number of missions I will write a World Post. Which is something that will effect the city and draw attention to certain parts of the city, asking more questions and giving others the urge to go and explore.

Finally, I've been toying around with the idea of a level system. Nothing too hectic, it's as basic as Casual, High Casual, Advanced, Veteran, Mod, Admin. These levels will improve your standing and renown throughout the RP, allowing you to do and know more. The higher your level the more dangerous, but important, your missions will be and the more information your character will be given in World Posts. I haven't yet decided whether to implement this so level progression hasn't been decided either.
