Hi, I'm new to GMing and I'm trying to find a reference of both core game concepts and world lore that GMs in the community would consider the essential foundation of knowledge for a GM to know.
Stuff that would be important most of the time.
Things like how to quickly throw together an NPC's stats if I don't have any pre-made, or what some of the most notable (in-world) locations and events are. The type that most people in the setting would find as common knowledge.
Pre-made reference materials or lists would be appreciated, but I'm also fine with book recommendations and page numbers of important information.
Thanks in advance!
