From Introduction:
Within a long forgotten stronghold buried deep beneath the earth, vast wealth and secret knowledge lie hidden, awaiting brave adventurers to lay claim to them. Powerful forces are at work in the fortress, presenting both opportunity and danger to intrepid tomb raiders.
The Gates of the Shadowmage is an adventure that takes place in an ancient warlock stronghold called Shadowhaunt, abandoned since its owner was defeated a century ago. The adventure offers players many opportunities and rewards, but may also put them in precarious moral dilemmas as they are dropped into the middle of a long-simmering war between two evil forces. Whatever path they take, at the end of the adventure they could find themselves with the use of a complex that contains doorways into other planes of existence, allowing for endless adventures in the future.
This adventure is designed for 4 characters of 5th level, but can be adjusted to work with groups of various sizes. A smaller group may want to bring along a berserker or priest NPC, depending on their party’s composition, while a larger group may encounter additional enemies in greater numbers.
No matter the size of the party, there are encounters in Shadowhaunt that are likely to prove deadly if not handled with the utmost care.
