And now, it seemed events had aligned just so.
He waved his hand over a swirling black mass, causing it to reveal a scene from the underworld. A warlock sat in a cave, staring impatiently into a bowl of black liquid. The demon watched as his own visage appeared in the bowl. "Greetings."
"Do you have it?" replied the warlock impatiently.
"It would serve you well to let things come in their own time."
"You're one to talk, manipulating time to your own ends. Now, do you have it or not?"
The demon let his temper flare for a moment, "Do not talk to me of time! I'm at it's mercy as much as any being, perhaps more so! I have simply found a way to reach through it's depths."
"Whatever," sneered the warlock, "did you conjure it or not?" The demon dropped a silver amulet through the portal in response and watched as it popped out the bowl, floating in the viscous liquid.
"The spell is in inside. I pulled it from a shaman just moments ago. You merely need to reword it's target. Now hurry, our window of opportunity will quickly pass."
The warlock smiled wickedly, "Excellent." The image of the demon swirled into blackness again, leaving the warlock to work his dark magic.
