From publisher blurb:
The Darkness Rising series continues with Powers of Light: Magisters.
The first in a series of volumes detailing the forces of good in the Great War, Magisters are the wizards of the powerful alliance of light. Spellcasters and wardens of peace, the Magisters are an ancient organization, filled with secrets, mysteries, and age-old pacts.
Able to cast back darkness with their mystical Wands and Staffs, the Magisters are a shining beacon of light in a world of growing shadows.
Become a Magister, take up the Light of your Order and protect the night against the rising menace of the undead. Become a mystical vampire slayer, a bringer of peace, or a sentinel against the rising brought by the Void - the terrible power of death and darkness.
