Generic Encounter Table for Pathfinder

I came up with a generic encounter table for Pathfinder (or for any 3.x d20 game, really) that takes into account the "safety" of an area. "Safe" areas are less likely to produce high-CR encounters, while dangerous areas are more likely. The specific encounter in question should be determined by the DM, taking into account terrain and the indicated CR.

Background and Elective Skills for Traveller

As indicated in a previous post, I prefer for Traveller characters in my games to be more widely skilled than the game normally allows. As such, I have instituted a system whereby characters get skills before entering any service (i.e., before the age of eighteen), and a small selection of elective skills not related to their professional service during adulthood.
