(For what it's worth - I give very few products a five star rating. Masks easily earns it.)
Masks: 1,000 Memorable NPCs for Any Roleplaying Game could be a candidate for one of the best GM tools ever, at least in my book. It is a 300+ page collection of NPC personality sketches that is not just a list of characters, but a collection of tools to adapt them to your own campaign and use them to the best advantage. It’s not only a book of NPCs, it is a book on how to NPC.
The entire first chapter is devoted to GMing advice – making NPCs memorable, “re-skinning” NPCs from one genre to use them in another, polarizing elements of the character to make them unique – and most importantly, how to not overdo it (these are supporting characters after all, and should never steal the show from the real protagonists). The lists of traits and “invisible keywords” at the end of this chapter, and the explanation of how they were used, will prime any imaginative GM to immediately begin customizing these NPCs before they even get to them.
After that comes the parade of NPCs, divided into three genre categories (fantasy, modern, and sci-fi), each of which are divided into sub-categories (villains, neutrals, and allies). Each NPC is fleshed out in an array of descriptors – Name, Capsule Description, Quote, Appearance, Roleplaying, Personality, Motivation, Background, and Traits. The descriptions are very concise, to keep the most important and functional elements of the character in the foreground. Many of the NPCs could easily be adapted to other genres with a bit of fiddling and tweaking (and advice for this is supplied in Chapter One).
If all of this wasn’t enough, the book contains a “name ribbon” running through it – a one-line list of names running along the bottom of most of the pages that a GM can quickly reference if a character name is needed on the fly.
While looking through this massive collection of character backgrounds, I found an additional use for it, as I caught myself coming up with story ideas to draw them into. I’m even tempted to challenge myself and choose some at random (they’re all numbered) and try to write a plot around them!
As a side note – I was pleased to discover that it was inspired by one of my favorite Dragon magazine articles of all time – “The 7 Sentence NPC,” by C.M. Cline. It appeared in the August 1992 issue, and I’ve kept a photocopy of it in my RPG binder for many, many years now.
I really can’t recommended this collection enough for any serious GM’s reference library.
