Demons don't hate you, not truly.
They are beyond you, an emptiness. Some simply express their natures- stalking and murdering, the wet spray of blood, the iron-stench that hangs like a red mist after the deed. Some take it slow. Coughs and pus and fevres and pains and bloodied bowels. They have much to show, much to inflict.
Others enjoy their wickedness, their accursed freedoms. Free of the shackles of gold and lead alike- though the telluric bones are another thing entirely. They want to share it with you. Yes, you, because you deserve it. And would it not be fair and nice if you shared something with them?
They hide in the skin, in the air. Glowing in shadows and fading in the light. Floating along the river of word-sounds, mirages of mnemoforms in the mind- was it there? No burly creature are they (unless it suits them). Is it telling you something? Or did you independently use your mind and heart, to derive an inevitable truth, one that conveniently converges with the sickly-sweet whispers emanating from the tongued-forks of Demons.
Let them in. Or don't. It matters not. They want to feel the sensation of flesh again, the warm embrace of skin and the rigid comfort of bones living.
Sometimes they wait for you. If you are so smart and wise and brave and strong, they wait for you to call them. You can extract careful assistance and forgotten knowledge from them. They know of the Dragons Metallic, the innermost desires of your desire, the forumlae alchemick that would throw open the doors barring mortal hands from the hidden compounds, the purpose of the sky-rings, and the elders who fashioned them with artifice and fear. They know of the betrayal of iron and the first of the giant-kin. The Elfin enclaves will not tell you that, you know? And all gods-fearing peoples know that they get their powers from demons, anyway.
The salts and smokes and signs bar them, keep the Demons in an invisible cage of your construction. Arriving in forms of eyes and weeping bark. They are forced to help you, of course. And for such an easy process. And they can help you so much more, if you just loosened the leash...
