I'm looking to craft a small binder of resources. Something to help me with my journey experimenting different tactics at DMing. Currently in my binder I have a list of names and personalities to pull from random NPCS. For fun I have a single page listing personality traits, positive, neutral, and negative ones I can mix 2 or 3 together to make an npc on the fly feel like his own guy if I'm stumped. Then the name list was a neat resource for me because it helped me understand the names I was picking. As an example, much of the Lizardfolk names I've come up with came from Nigeria which has a ton of cultural inspiration I can use to spin into, breathing life and personality into it. So the big question I'm asking is what other ideas can you guys think of to put into this book that can help me give my world personality or keep the game moving at a steady pace? The obvious parts of the session notes and maybe a small map or reference of the area.
