The moment he touches it, the metal begins to glow, starting with the hilt of the sword and expanding in an instant to fill the room. His companions are no longer visible, and the columns of the room stand intact, with none of the piles of rubble he was searching through a moment earlier.
Lariel's grave, too, is gone. In its place, Blai can see an angel, badly injured, lying on the ground, hand gripping a sword; in the same moment, he is the angel, and through the angel's eyes he can see a crowd of people, people he had come down from Heaven to protect, standing around him and closing off all escape. The wound on his chest, or perhaps the angel's, is bleeding again. To one side of him is a girl, terribly wounded, and a dreamlike sense of certainty tells him both that every other person he can see betrayed him, tricked him, left him to die the final death of an outsider, and that this girl alone fought by his side so that he could have even the tiniest chance of victory. The others jeer at them, jeer at him. They will die here, they say, and he will have bought nothing by his sacrifice.
There is anger burning in the angel's chest, fear twisting in the angel's stomach. He is running out of time, and he knows it. The same sense Blai would normally have for his own spells tells him that he has a healing spell left, a weak one. It would probably not be enough to save the girl, even if she managed to escape. It would certainly not be enough to save him. Or, with his other hand, he could take his sword, call on its magic, and try to strike down the traitors. But even if he could somehow kill every last one of them, he knows there is another power, far stronger than any of them, hiding somewhere far beyond his reach, and it is too late for him to defeat it. Either path will probably be futile, but inaction will certainly be.
