I have made a basic idea behind the location (a restaurant in this case) in which the RP will take place so we should start thinking about the characters. "Black Moon" veterans are those with both fighting ability, needed to survive on the streets, and the brains which are needed to actually become a member of "Black Moon". Since we are handling both a cover service establishment (a restaurant) and large scale smuggling one of the character would need to be a "people's person" while the other would need to have some accounting and management skills.

With this tips make a character with those:
A name.
At least one alias.
A "Black Moon" name. Those are used when dealing with those which are not directly in the same part of the operation like the smugglers which we will be dealing
The race of the character in question (human preferred).
A description/picture for appearance.
A bio.
A basic personality.
A list of skills and abilities that the character has.
Anything other you thing might be important.

I will make my own when I see your one.
