"I will bear the burden, this fel power must not be allowed back into circulation and I do not know if it would have ill effects on you should you hold onto it." He gritted his teeth and planted his feet as firmly as he could and began to absorb the dark energy, hissing in pain as he did so and his wings and then his body sparked with black electricity - it felt like his entire body was on fire even with the protective runes.
Dropping to a knee, the black electricity crackling across his form slowed and ceased. He breathed out a puff of smoke and took a moment to center himself as the pain subsided and as his body healed he saw it in his mind - Icthultu, the old one whispering faintly to him. "It...will take some time for my body to adjust to this, as an Archon my physiology is not compatible with dark magic and my immune system with eventually convert it via transmutation into light. I...saw the old one." Standing up unsteadily, he summoned his spear to lean on for support.
"This is far from over, Deathwings will offer this 'gift' to every wicked caster or magical creature able to bear the initial infusion that he can find. Should a true Lord of Chaos take up this cup, I shudder to think of the devastation that follows."
