A Web Enhancement Adventure Site for Complete Adventurer
Complete Adventurer offers a wealth of new spells, prestige classes, feats, and magic items for bards and rogues. According to a sidebar in the description of the Fochlucan lyrist prestige class, a college for bards is located on the shores of Loch Firrnen, a few miles from the town of Oakenway. This adventure site details that haven of peaceful study.
Secrets of the Fochlucan College is an adventure site that can be dropped into any area that has a large, clear lake. A variety of adventures can take place here, since outsiders frequently infiltrate the college to search for its secrets. As always, feel free to adapt the material presented here as you see fit to make it work with your campaign.
