I am on the HOME STRETCH to complete the mega-dungeon, Underport: Abyssal Descent! Currently there are 198 separate encounters, a pirate port, underground town, small keep, and a deep race dwelling adjacent to a vast subterranean land.
I had hoped to be all done by this month, however, since it is now December 31st, that is not going to happen.
Underport is my top gaming priority right now and I expect to have it finished early in January. The wait will be worth it as this dungeon is suitable for starting out a 1st level party or shuttling in your high-level characters in search of a challenge on the edge that represents significant chances for character death... (AND commensurate rewards!)
