How do you say keeper of the flame in Navajo?

"Keeper of the Flame" is actually a sacred name associated with one of the Holy People, and therefore, is not a name associated with humans. He is the one who gave the Navajo knowledge regarding the building of fire; hence the expression for inquiring who has the ability to make fire:

Heesh bi kleel holoo? Who possesses the ability to make fire? Haashchʼééshzhiní -- Black God, creator of fire and the stars.

Dilyéhé, the Pleiades, are depicted on his temple.
