Disciples - The Fourth Age Dark Shaman, #1

Elf Queen Aradia remains in Elvalon, forbidden to return to the land of Nostraterra by her patriarchal grandfather. However, she knows of a terrible, dark presence exists in Nostraterra, and also that the races are bound to wage war against each other soon. Training with the Elven weapons master, she passes the time until her magic is needed again. As darkness begins to infiltrate the lands of Elvalon, Aradia's grandfather must seek her help in trying to find out how the dark magic is getting past their magical defenses.
Meanwhile, Prince Alfrahil, still recovering from the ambush that nearly killed him, is enjoying a false peace with his new lover, Findalas. When new, targeted attacks begin against valuable men of the city, Alfrahil, the king and the first minister are baffled. Findalas suggests that they consult with brother Caedrasp from the Brotherhood of the Cold. Making a deal that may cost him dearly, Daerahil set out for Tarin Nazar: a keep within the forest realm of the Elves.
But can he emerge victorious against an ancient evil of immense power?
