From publisher blurb:
A Trial by Fire & Ice
Come and oppose cultists bent on controlling the world, go on a sea voyage to the Isle of Pleasures, fight off cabalists piloting an iceberg ship, and explore Azer Tower on the Plane of Fire. While there, seek the destruction of a crystal relic while trying to avoid death at the hands of an undying assassin who never quits. Challenge your players with roleplaying, puzzles, combat, and exploration using this quick-start quest.
“Fire & Ice” is an adventure for the 5th Edition of the world's most popular roleplaying game that provides level 8-10 characters an unexpected quest. Tasked with destroying a minor artifact, can your PCs finish the adventure that another adventuring company all-but perished on? A nefarious and eternal nemesis is on their heels to make certain they fail! Besides high adventure, 5th Edition Modules: Fire & Ice offers the GM a reusable and unique island locale that safely intersects with the Plane of Fire.
