Canol Madreth is a small, remote, mountainous country at the centre of Gryonlandt. It is governed by an elected parliament called the Heindral - and by the sombre tenets of the Church of Ishrythan.
Then, one fateful day, ominous clouds gather over Canol Madreth, and - mysteriously affected by whatever brought them - impetuous Brother Cassraw is transformed into a fiery religious demagogue. Suddenly the stability of the whole of Gryonlandt and beyond is threatened by his strange, compulsive power - and by the dark, primitive religion he begins to preach.
Only Allyn Vredech, fellow priest and lifelong friend, senses the terrible truth. Struggling to accept the world-destroying nature of the force that has possessed Cassraw, he must fight not only for his own faith but also for his very sanity - as he is drawn into worlds far beyond Canol Madreth. Worlds that cannot be . . .
Worlds that exist only in the dream of the Whistler . . .
