Guch Ydroma was a male human inhabitant of Jedha who claimed to have been touched by the god of his Phirmist beliefs during a desert pilgrimage, and to have been granted the mystical ability to conjure water "as if from the air itself." He visited the many temples of the Holy City, summoning water and sealing the liquid into bottles marked with the temple's name, including Roalj temple. Ydroma then traveled Jedha selling these bottles to both believers and the thirsty alike. Ydroma was selling his wares in a square in Jedha City when the rebel agent Jyn Erso first met the Guardian of the Whills Chirrut Îmwe across the square.
