Thank you for your comment. It is appreciated. For the purpose of running the module - answers to these questions are found within the text of the module (using blue diadem, significance of runic writing, Martian race, ect), but the layout could have made this info more apparent. For creature levels, as per Shadowdark, HP divided by 5 (4.5 technically, but here rounded up) will give the creature level. Once again, thank you for the feedback! I hope you get the chance to run the module in the future.
