"Secrets" of Tortage

Most people have gone through Tortage a few times.  Including characters I've deleted, I'm guessing I have run around the Barachan Isle more than twenty times (including a few times to make notes for guides and such).  Despite its familiarity, it's still one of my favorite places in the game.  Partly due to characters you interact with and partially because the area was so detailed and full of interesting quests.

This post is going to focus on a few special quests.  Special because it requires the completion of another quest before it becomes available, its reward is a blue item, or both.  There's also a few Night bosses sprinkled about White Sands Island, the Volcano, and the Underhalls.
