Druj

Druj is a former underling of Jahy, she now runs a successful company in the human world.

Druj is loyal servant of Jahy and would listen and agree to everything she says. She is willing to let Jahy test out her weapons on her. Her trust and opinion of Jahy is so big that even when Jahy acts on a selfish desire that could even harm or be negative for Druj, Druj ends up always believing its something that Jahy was trying to teach or its something Jahy was doing for her.

Druj's name comes from Zoroastrianism where it means demoness. It can also mean lie or deceit, one of the major vices in Zoroastrianism.
