From publisher blurb:
Flik Silverpen's Guide to the Sky Garden is a point-crawl adventure through a giant-filled floating island. This adventure will work great as a one-shot, but also connects to the Dragon Town / Darkness Below campaign, picking up right where the Errant Tower (FSG 08) left off.
An ancient relic known as the Star Heart is the only thing able to destroy the Darkness Below once and for all. Unfortunately, it's protected by super-powerful Astral Giants way, way up in the sky on a floating cloud island called the Sky Garden. The adventurers aren't the only ones after the Star Heart either. There's a legendary thief, a greedy blue dragon, vulches, dodo knights, bog frogs, and a bunch of other dangerous creatures who call the Sky Garden home.
This adventure is filled with whimsical illustrations, an easy to use point crawl map, lots of fun magic items, including a bunch of strange plants, some seriously weird NPCs, and a legendary boss battle. Combat encounters include references to comparable 5E monster stats, otherwise, the zine has everything a DM needs to run this crazy dangerous one-shot!
