Yes. It's mainly because I already have images of them and their personality in my head, and egoistic me doesn't want anyone changing his vision, haha. I plan to do Character Sheets for every major NPC that will show up in multiple people their posts, and I'm probably going to ask the others to try and do the same. I hope it improves consistency between NPCs behavior in posts. I will probably try to catalog as much as possible, and make a "big bad monster book" with extra information.
