On this other site, I could create character placeholders, if you will, that would represent NPCs. It was essentially the 'shell' of a character, complete with pic and description, that the PCs could view at any time. However, the character was assigned to me, the DM. This would also allow me to make a post as if I were that NPC. Players would see the post was made by the NPC and when they read it, it even had the NPC's pic assigned to it, etc.
I've created a temporary 'fake game' so that I can tinker with the GP mechanics and get a feel for the site and how things work (and of course, how they different from my past site). Thinking I had found the solution to my dilemma above, I noticed how I could import a character from my stable into my game. So, I assumed that I could just create NPCs as if they were my characters and bring them in this way. Nope. After inserting the first character, the option was gone. Clearly, this isn't how it's meant to work.
Is there a way to create other 'characters' in the game that I portray, as described above, or is this simply not an option?
