Me likey.
Her minors would probably be offended having to be her attendants anyway.
But I think I'll add my own little touch. Maybe her influence passes through the land whenever a baby is born, and she looks upon the child. If she finds it to be particularly beautiful, then she scoops it up her mountain, and in return for the child's services, she blesses that family with great fortune and resources.
The servant is matured to the age where she perceives them to be at the height of their beauty, and then they won't age from that point; if they want, they can relinquish an immortal life, and if they do, they are rendered mortal (and memory of their parents is restored), but any family they establish will be blessed by Uburra-Namall from that point.
The others will also have minions.
Khadai will have creatures called Shadows. They look, to the deities, like people composed of darkness, but they are invisible to normal people. They alert Khadai if mortals fall to the temptation of one of the seven-sin deities (Vai, Prasim, Eda, Desra, Nasta, Slomna, Indiva). They also spread rumors.
Jassi will have priests and priestesses who she appoints within every village. Only the most pure and chaste may be selected, and they are chosen from seven years of age. These will be the means by which religion is established within the land. She will also touch some and bestow them with various other gifts, such as healing, prophecy, speaking to the divine, etc.
And Jissei will touch some to make them doomsayers, prophets of impending disaster. He will also be the divine force that punishes enemies of Uburra-Namall with curses, which last on that person for a generation; those who seek to put curses on foes who rightfully deserve them will invoke Jissei (while those who wish to put curses on people out of envy, jealousy or spite would invoke Khadai)
The Seven-Sin Sisters are also Khadai's minions. They will serve as her priestesses, perceiving which sin affects a person most, so that she may tempt them best.
And I'll have to think of something for Hargonon (the war deity) when I make him.
It's gonna be very interesting...
