The greatest friend of the water elementals, the Hydoemi, the Fairy Sirena's land extends into the very waters, including the Serpent Sea and the Emerald Sea. Bordered on the west by the Rhun and the east by the Suirebaire that flow from the Lornloch or the Moon's Eye in the Dark Wood, gentle Sirena's people are also sea-lovers, who dare to brave the dangerous waters that circle most of the Twelve Kingdoms.

On the western border of Sirena are the Cauldron Fens, formed where the Rhun and the Serpent Sea mix. Legend claims that the boiling black blood of the Sea Serpent eddied against the land and stagnated everything it touched, hence making the fens. Legend also claims that the chain of islands to the south west of Sirena, known as the Serpent Isles, is the carcass of the great creature that Guilian Silverbow slew (and for which he was rewarded with a chip of emerald from the Serpent's eye).

Like the people of Dalfinn and Goewinn, the denizens of Sirena refuse to speak one way or another about the creature they guard, for there are things a man does not speak of lightly. Regardless, the final westmost island, known as Blood Isle, is formed entirely - so modern scholars assure us - by a semi-dormant volcano.

Sirena herself refused a grand castle in which to make her home, but accepted the gift of the Hydoemi of half a shell of Cianen Gwyn Tor, the greatest of the seelie mercreatures who when he died bequeathed himself to Sylvaenn, Lady of the Deeps. The other half of the shell remains in the Hydoemi court, beneath the waves of the Emerald Sea, as does Cianen's pearl.
