In Fall of Angels, Modesitt moves deep into Recluce's past to chronicle the founding of the Empire of the Legend, the almost mythological domain ruled by women warriors on the highland plateau of the continent of Candar. He tells the story from the point of view of Nylan, the engineer and builder whose job it is to raise a great tower on the plateau known as the Roof of the World. Here the exiled women warriors will live and survive to fulfill their destiny. Here a revolutionary new society will be born...if Nylan can get the tower built and defenses in place before the rulers of the lowland nations come with their armies to obliterate them all. And if Nylan can learn to control the magical powers that are growing within him. Thus Modesitt relates the story of how magic comes into the world of Recluce, in a fantasy novel destined to please the growing Recluce audience and win new readers to the series.

Two radically different magics--The black of order vs the white of chaos--this is the central facet of each tale in the saga. In each book the protagonist is either of the black or white persuasion, and in a few there is a grey area of magic. In Fall of Angels, Modesitt explores the side of order, the black magic of healing and building.
