Edelgard
She could no longer afford to keep up the monstrous strength that had made her latest moves so effective, but still she swung with all her power. She felt the doping leave her, soreness and shortness of breath replacing it (pain, but only a fraction of what it should be, thanks to the air thick with astral taint), but brought the heavy head of the polearm against the thing anyway.
Too late. The light enveloped Edelgard, flooding all her senses with a wretched cacophony. The force pushed her away, diverting her strike as it burned every inch of her, but she refused to loosen her grip. She roared as she failed to keep her feet on the ground, but the sound was amorphous with everything ringing in her skull.
In an instant, she couldn't tell up from down, but no! No, NO! Edelgard protested to herself, trying to hold on. This bastard, these monsters, whatever spawned them! They'd die before speaking for her! They were no good and she'd tear them all apart if she had to, and fuck her peace and damn their words!
The spirit was willing, but the flesh was weak before this onslaught, and cried out as it overtook her. Edelgard, charred and beaten, went tumbling through debris and dust, crashing through one, then two walls before her consciousness drifted to silence. Her spear remained in her hand.
