“The immense, rambling complex of Castle Xyntillan has stood in its mountain valley for many years. Built over several generations, it has now been deserted by its former owners, and left to time and the elements. However, that is not the end of the story, for Xyntillan’s fabulous treasures and Machiavellian deathtraps continue to fascinate the fortune-seekers of a dozen lands – and never mind the ghost stories!”
From the introduction of Castle Xyntillan, by Gabor Lux.
Castle Xyntillan is a sprawling mega-dungeon module created by Gabor Lux. This fine looking tome sat on my shelf for the better part of a year, something I flipped through occasionally with marvel – for it is truly marvellous – but as 2023 rolled around the gothic castle called out with its ghostly whispers, and I started a new campaign using it. My plan was to run it for six months, mastering the B/X rules as we go, which I did, and completed the Campaign in July 2023.
I ran the game every week on Thursdays at 6.30pm GMT / BST
We used Old School Essentials Classic Fantasy Tome for our rules, and played as close to the rulebook as possible with very few house rules.
