Insomnium barely felt the lick of the flames, but combined with the draining of his life, it was wearing him down a bit. Before he could cause himself more harm, however, a voice spoke in his head with the simple phrase, 'enough'. 

Suddenly, the demon's body begn to shine with dazzling light, before darkening into an empty void. The void soon took a humanoid shape, though it was hazy, indistinct, and had two glowing blue eyes. Abraxas' flames, held back by a strange, invisble field during the shift, now surge forth looking as if it was about hit the shadowed figure, only to go right thru it and into a near by building. Azous stepped out of the flames path, looking no worse for wear, and laid down on the ground, as if he was falling asleep. A few seconds later, he was, seeming to be out like a light, despite the fact that he was facing a giant demon in battle.
