Philip Wittebane kept a journal of his life on the boiling isles, dating back to when he first arrived in the 1600s, to his quest of finding a way back to the human realm. Before his mysterious disappearance, he donated his diary to the Bonesborough Public Library, where it ended up in the forbidden stacks among thousands of other books that were old and forgotten. Years later, Luz Noceda, the second human to live on the Boiling Isles, sought to find the diary in the hopes of learning more about Philip Wittebane and how he came to the isles. With Amity's help, they were able to find the diary, only to discover its pages had been eaten by mice. However, the knowledge was not lost because the mice in the forbidden stacks were known as Echo Mice, which meant they could playback all the knowledge they consume.
The diary contained deisgns for the portal between the human and demon realm, and a map leading to the now depleted Eclipse Lake where Titan's blood could be found.
- "My journey through the Demon Realm is far from over. But today I humbly donate my journal to the ages."
- "Entry One: May 21...I think. My Name is Philip Wittebane. And I have found myself in a world so horrid and so fantastic, few minds could have dreamt it. If only those at home could see what I have, and perhaps they shall. For the more I learn about this realm, the more I am certain I can harness its strange powers to return home. Today, I begin recording my journey home to create a portal back to the Human Realm. "
- "After five years, I had finally found it. A power source so potent it can pierce through realms. Titan's Blood. There are old tales of lakes reflecting green trees and blue skies. The Titan's veins run through the land. And many believe that these wild portals are created when a little of its blood leaks into the water. That is how I came here. So that is the first place I shall look. I will journey back to Eclipse Lake."
- "My journey to Eclipse Lake has been a success, and yet, a tragic failure. The tunnels were filled with a substance known as Fool's Blood. It signifies a decaying rain. I was lucky to get out alive. My companions were not."
- When 'regurgitated' through the Echo Mouse, the entires of the diary greatly resemble projections of the lanterna magica, the magic lantern, one of the earliest means of image projection. Much like Wittebane himself, these devises flourished in the 17th century.
