I'd like to add a list of creatures, monsters, and characters to a Fate project, like the D&D Monster Manual. I understand that the GM usually writes NPCs custom per game, but I want to present some sort of list of statistics/values/aspects. This is for two main reasons:

1. Worldbuilding: There are a lot of different sorts of non-human (and not-even-remotely-human) creatures in the setting, and they're all fair game as far as conflict is concerned.
2. Workload: If I can, I'd like to make less work for the GM, why force them to make up stats for creatures that I'm already presenting information for?

How should I present the creatures? A single stat block for each? One for Nameless, Supporting, and Main NPC levels? Should I count up a "stat value" for each and weight them that way? Or just write whatever makes sense and leave the encounter balancing to the GM's discretion?

I'd prefer examples of actual bestiaries/NPC lists, but I'll settle for similar presentations in Fate works.

In what format are creatures/NPCs normally presented?

A single stat block for each? One for Nameless, Supporting, and Main NPC levels? Or are they just described however makes sense, leaving the balancing to the GM?

I'd prefer actual example stat blocks from actual bestiaries/NPC lists.
