Steam Tunnels of Serraine in Threshold issue 39
The module that was developed during my Mystara campaign was recently published in Threshold issue 39. It will also be released later as a stand-alone adventure module.
This Expert-level module is set in the Undercity of the flying city of Serraine and features 60+ rooms on several intertwining levels of service tunnels and ancient underground habitation areas.
