This is a set of worksheets which I have designed for planning out Adventures. I've used it for The Shadow of Yesterday, Serenity, Traveller and GURPS, all with more or less equal success. The original design was for The Shadow of Yesterday, hence the reference to Secrets and Keys in the character summary.

This file very clearly isn't intended to act as an at-table play aid, but instead to function as a planning tool which you can print out and fill in.  Typically multiple copies of the Key Scene Worksheet are needed.

Because I generally run event-based adventures, I don't use the map index a lot, but I do on occasion. The NPC Index is a document which I maintain throughout the life of a campaign.

The Key Scene Worksheet has been broken out into a separate PDF form, which you can fill out and print, so that your in-scene notes are easy to read. You'll also see an example of a filled out sheet.

If you use this in your game, please leave a comment below to let me know how this worked for you. I'd love to know what features worked and what needed improvement.

Updates

I've made an OpenOffice writer template for planning out your adventures. I have also incorporated features from Robin Laws' Laws of Good Game Mastering to plan out your transitions between scenes. This makes the templates better for mysteries, as well as the Set Piece and Branching adventure structures described by Mr. Laws.
