The demon stood still for a minute; he awaited what you would do next. He had run his mouth, and he knew it. The ball was in your court now. And you would be acting upon it.

"I shall keep it short, aberration; both of us know that one of us shall betray the other sooner than later. Thus, I shall be the one giving the stab; nothing too personal, you would have done the same with me.''

A scream of feral rage came from the demon, but you quickly blasted him with magical energy, which threw him back against the wall.

His cultists, initially shocked that someone had dared to throw about their master, tried to join the combat, but their physiques, weakened and corrupted from years in the demonic wastes, were easy pickings for your own cultists.

One of them did break through, wildly trying to stab at your umbral form, but to no avail; it was amusing, really. You were a long way from being corporeal, but your hands could sometimes leave their disembodied state. You lifted him up by the neck, though you lacked the strength to strangle him, and sapped the vitality from him, crumbling into dust, leaving not even a skeleton.

You then turned your attention back to Kranazim, who was recovering from the wall crash. You began summoning up an even greater spell, one which made the runes and profane etching upon his chest glow. Air began to flow weirdly; the temperature dropped and rose within seconds. As you began the process of binding this demon to you, if successful, he would be forced to obey you for as long as you kept in mind not to let his commands be left open to interpretation. And it would allow you to send him back to the depths of perdition from whence he came whenever you pleased, and to summon him forth once more.

Roll a 1d100 [DC75] To see how the binding shall proceed.
