In the world of Ice and Fire there are many religions whose gods are quite similar. In particular, here are some of the gods of water and sky/weather:
Water Sky The Ironborn The Drowned God The Storm God The Three Sisters Lady of the Waves Lord of the Skies The Rhoynar Mother Rhoyne The Storm Kings The sea god Goddess of the wind
One of the concepts in the books is that many of the gods are given different names by different peoples, such as the Many-Faced God who is called 'the Black Goat', 'the Lion of Night' and 'the Stranger'.
Do the books also explicitly equate any of these water and sky/weather gods?
