I've never heard of the Age of Worms setting/adventure path and I noticed it isn't available @ drivethrurpg.
Was it something that was published in one of the WotC magazines?
It was the second Adventure Path (after Shackled City) in the magazines. Rather infamously a meat grinder, starting with the first dungeon that chewed up 1st level PCs like a low-level Tomb of Horrors (fear the 3e swarm rules... FEAR. THEM!) and going on to fight against dozens of dragons at once (not a typo) and against an enemy armed (heh) with the Hand and Eye of Vecna.
