I am very excited to see another 5-Star review for an adventure I wrote from prolific RPG reviewer, Endzeitgeist! Many thanks for the fantastic thorough review!
"The Unreachable Terror" is a Mini-Dungeon adventure designed for 4-6 PCs of 9th - 10th level. It was a fun experiment pushing the Mini-Dungeon format beyond the typical "dungeon/encounter" style by creating an sandbox environment to be explored including an overworld map, settlement information, a trail of clues to investigate a mystery, and challenging encounters to help bring the experience to life.
