- "If the enemy did not laugh themselves away, it was said that Mother Rhoyne would whisper the enemy's secrets to her children and the Rhoynish wizards could raise watery walls to drown their foes."
The Rhoynish water-wizards were powerful worshippers of Mother Rhoyne.
During the Rhoynish Wars, Mother Rhoyne was said to whisper the secrets of the Rhoynar's enemies to them, allowing the water-wizards to raise walls of water with which to drown their foes. The water-wizards used the same magic to raise enormous water spouts to defeat the dragons of Valyria.
