A Bao A Qu is a Malay mythological being described in Jorge Luis Borges's 1967 Book of Imaginary Beings, claiming to have found it in a book on Malay witchcraft. His skin is fuzzy like the skin of a peach and his color goes from transparent to bright blue.
He lies dormant on the first step of the Tower of Victory in Chitor, a tower of many spiraling steps and of which one can see the most beautiful scenery in the entire world. In a translucent amorphous form, he awaits for a man brave enough to climb the tower. He shall awaken from his slumber when someone arrives and will follow the climber on their journey. The majority of the time when the climber doesn't reach the top, he will become transparent and descend to the tower's bottommost step again; he softly mourns, sounding like the rustling of silk. If the climber gets to the top, they shall achieve Nirvana.
