A flamegun-wielding Portal Guardian priest is the key to preventing the invasion of black-armored soldiers from incoming starships, with the help of a child Oracle, a man of the Old Blood, and singing priests from a distant world. Vena, Portal Guardian and priest extraordinaire, is assured by vinemaster Perry, through a foretelling, that she will prevent the invasion of Arcan by black-armored soldiers. With the support of her beloved Fenn, Patroller and priest; Holden, Man of the Old Blood, bound to the ancient temples; Bennie, the young Oracle, haunted by visions; and corvonen Wake, tied to the power of singing priests from another world, Vena must stop an invasion, learn why ancient temples are the target, and identify friend from foe before the attack across every territory. The foretelling insists that she will use wind, lightning, and starlight, and the voice of her departed Oracle friend Oonagh keeps whispering, “Wait till starfall.” How can Vena accomplish the impossible?
