Will be running End of Eternity soon and I decided to make custom wandering monsters for each of the islands. The list is far from perfect but I felt it better reflected the different environments of each islands. Also the list is not in EL order. But, still, I thought I'd post it in case someone else wanted to use it or customize it further for their game.
I took out 3.5 MM creatures that were not also in pathfinder and added a couple of other creatures from the LoF beasteries.
