The third, and by far the largest, part of the "Isles of Dread" campaign was part three, "Exploration of the Islands". This involved the characters travelling around all of the smaller islands in the chain, engaging in various mini-quests, and generally exploring. The party are now on their way to the final one of these islands, and currently engage in combat with a shoal of reef sharks intent on blood. But that's close enough to completion for this post.
The fourth and final part of the campaign, "Temple of Elemental Evil Fire" beckons. It shouldn't take so long. Unfortunately, it's also the section that I have yet to write...
