This is a fantastic adventure that perfectly captures a classic sword-and-sorcery, treasure-hunting feel. The opening hook: a tavern brawl over a mysterious map leading to a wish-granting gem is a brilliant. I think it is an effective way to start the action immediately.
The overland travel section is a real strength. The design encourages exploration by having players piece together clues to find the shrine's location, and the timeline for Blackguard Rafael's own progress adds a sense of urgency to the journey. The Lost Shrine of Tolmazan is also well-designed; the relationship between the ghast queen and her pet basilisk creates a particularly interesting and dynamic encounter.
The two-column layout is clean, and the public-domain art choices give the entire document a great, old-school zine aesthetic. A very clear and highly playable adventure. Well done!
