Here are a few creatures from the various Inner and Outer planes as gleaned from various sources, and finally compiled into a 2nd edition-esque format that is usable and fun. In particular, not all 1st edition monsters made it to the 2nd edition, and here is one solution to alleviate that problem. The stats given here are by no means "official," but they are pretty close to said official sources (mixed 1st and 2nd edition sources, which can be quite different at times), and I welcome any remaining players of 1st or 2nd edition rules to try these creatures out.
