Caverns of the Dorgel Mountains is/was the finale in Filbar series. It features Lexicon Meridius the Ancient Red Dragon and scourge of the Dwarf Lords (F4 & F5). This large adventure represents how I look at the difficulty of taking on the deadliest dragon of the Prime Material plane. Will your party return to the Halls of the Dwarf Lords to help aid them one more time?
This adventure doesn't have any pending change requests.
