There are two types of characters that we would like suggestions for: Cameos and Extras.
Cameo characters are intended to be fully precreated and made available specifically for MUSH newbies. They are not generally intended as permanent roles, more as a way of trying out the game. ICly they are supposed to be more minor characters, suitable for getting your feet wet with. Ideally, they should be roles that have an easy time interacting with a lot of different people, rather than relying on for example the members of a single house.
Extras are basically named NPCs specifically intended as characters that can be emitted or referenced in roleplay when you need someone fairly generic but you’d like to have a name and some details to work with. They are not intended to ever become PCs, and that way they can be used more freely. For some more information, and some suggestions that we will be adding soon, see this forum topic.
If you have any suggestions for these types of characters, feel free to submit them via +help cdb submit. When it comes to the Cameo characters, we would also love some help with CGing the ones we decide to create, so do indicate in your submissions whether you are willing to do so as well.
