A legendary book, written by Valhadis about 3,600 years prior to the beginning of the campaign. Reported to be an exploration of the brain less as an organ and more as the lens of perception and as the ‘throne of dreams.’
Count Lowls was known to possess a copy, but gave it to Dr. Losandro in exchange for taking on a five new patients, former associates of his. Within, she discovered a process through which chronic dreams might be drawn forth and disposed of, like psychic gristle.
In Dora’s psychometry vision of Dr. Losandro’s office in Chapter 22, the party learned more about its use in two occult rituals that occurred on 17 Lamashan. It seems that its use (or misuse?) can cause the creation of oneirogens.
In Chapter 35 (Part 2), the tome was claimed by the party after they defeated the Tatterman. Dora took it into her possession.
