He steps up to the wall and presses his hand against it, even though it hurts and makes his skin come apart into curls of smoke. He feels... helpless. He does not like feeling helpless.
Imrainai is so important—a friend, a good friend, the first one he's ever had, the first person he's ever really truly deeply cared about—he wants her to be safe, more than he can ever remember wanting anything, even more than he wanted the things he shed his mortal flesh to gain—
—And then, all of a sudden, his half-disintegrated hand snaps back into full solidity. He can feel water against his skin.
He has only a moment to notice the change before he feels his world come undone.
It's a little bit like stretching out after a long sleep, or stepping out into the light after a long time in the dark, or taking a full breath for the first time after centuries spent underwater. It's wide and wild and dizzy and painful. The ground shakes, and he falls to his knees in a pool of shadows. He can't keep hold of his shape; it flows, dissolves, comes back together and breaks apart again. He is a boiling lake of black smoke and green fire.
He breathes. The whole bubble breathes with him.
And then he just... reaches out, and... the wall reshapes itself, stretching out a long pathway of air toward Imrainai.
He's not sure if that's what he should be doing. He's not sure what he should be doing. He has... so much to say to her, and no idea how to even begin to articulate any of it.
