History
In the days of pre-Weeping War Myth Drannor, the monks of the abbey of Deneir created a masterwork manual of bodily health. The enchanted book was placed in a lockbox of the abbey's chapel. The box remained unopened past the destruction of the City of Song and the book was still there in the early-to-mid-14 century DR.

In 1340 DR, one of these magic books could be found within Mantor's Library, of old Phlan. The book belonged to the library's former master who was a health nut.

In 1357 DR, another manuals of bodily health surfaced, hidden in a shrine of Mask in the sewers of Tilverton and not far from the city's thieves' guild lair.
