The Sun King's Palace

A crumbling tower hides on the Sunbroke Sea. The last relic of the second sun in our world. Sail out on the full moon and reflect its light with a golden mirror. Follow the trail to its end and enter the Sun King's Palace. A dungeon crawl unlike any other. Explore an ancient, elven palace that has fallen into the Abyss, talk to the weirdos that inhabit it, and uncover its many secrets. It's fully statted for OSR/adjacent games and each statblock has page numbers for the 5e Monster Manual. If you're looking for a dungeon with a focus on roleplaying, conversation, and exploration, the Sun King's Palace will scratch those itches. - from the publisher's blurb
