After many Birthright campaigns, and many hero-kings reaching the highest level of power, I wanted to give my players a shot at taking on the Gorgon!

Now, apart from the many considerations about the "readiness" of the Gorgon, and how to even get near enough to meet him, what kind of famous (or less famous) dungeon/fortress/lair would you use in this case?

I'm not looking to draw the whole thing from scratch, just looking for a good map/adventure to modify for my purposes.

The best I found so far is an old MERP module called Dol Guldur... that seems to fit perfectly with my purposes, but I was wondering if anyone has some suggestion.

cheers!
