Shadow of Azzagrat (3.5e Invocation)

''Shadows made Graz'zt, and shadows make Azzagrat. Shadows serve you, as they serve the Dark Prince.''

As long as you know this ability, you are accompanied by a creature identical to the one created by an unseen servant spell. It can be commanded to vanish as a move action, and can be returned to your side with another move action. While it can be given orders to do a task, it cannot travel further than Medium range in distance from you, or it vanishes. The creature can also be commanded to glow with a red Abyssal energy, which has the same effect as a light spell, or to stop glowing, as a swift action.
