The Hyclades is a river of the southern continent which empties into the Sea of Torments. It is not far to the east of Beryl, the most ancient of the Jewel Cities. The river is mentioned just once, in The Silver Spike, and no details are supplied about it or its environs.
The Hyclades is the second named location in the long, overland odyssey traveled by the demon called Toadkiller Dog, who was following the trail of his new enemy, the Limper. After swimming the River Bigotes and then the Hyclades, Toadkiller Dog continued eastward, crossing, in order: the Rani Poor desert; the lifeless landscapes of Barbara, Laba Larada, Khun, the Canyons of the Undead, and the ruins of the temple city of Marsha the Devastator; the populated province of Karsus; the Plain of Dano-Patha; the Mountains of Sinjian; and finally, the Straits of Angine and onward into the northern continent, to the Tower at Charm.
