This is such a complete package! Great map and detailed areas, magic items, and even a patron! Feels very Appendix N as well. Uses Shadowdark-isms very well!
A few favorite things:
- OF COURSE, the shifted eras for each room. I like that they're written as suggestions, cuing the GM to be creative!
- Astral Gem's high risk and reward
- Time's Needle itself being the pin between times and a very cool treasure
I ran into a couple immediate questions. Can Yasha-Gok be freed (and eaten :))? Is Time's Needle just plucked from the air? What happens, time-wise, when it's taken? But those could easily be ruled on the fly! Very fun submission!
