Turn 4 of 9

Call Cassiel back and ask what they are

Your voice catches them three steps up. "Cassiel." The name rings oddly in the stairwell, bouncing off the black glass walls, and you watch their shoulders settle — not a flinch, not a startle, but a settling, the way a bird settles its wings when it decides not to fly. They stop but do not turn. The spiral staircase holds them above you, and the morning light filtering through the tower's walls splits their silhouette into bands of dark and amber, and for a moment they look like a figure in a stained-glass window: beautiful, flat, without depth.

"What are you?"

The question leaves you before you can shape it into something careful, and in the silence that follows you hear the tower around you — the faint vibration of wind against glass, the distant rhythmic scrape of Yrenne's grinding above, and beneath it all, a low hum you have never noticed before, or have always noticed and never named. Cassiel turns, finally, and their face is unreadable, but their eyes are doing something you have not seen before. They are considering. Not calculating — considering, the way a person considers whether to trust someone with a weight they have been carrying alone.

"That is a larger question than you think," Cassiel says. They descend two steps, so that you are nearly eye to eye, and you can see the fine texture of their skin, the slight unevenness at the bridge of their nose, the small scar beneath their left ear that you have never noticed in nine years of shared meals and silent corridors. These are the details of a body that was lived in, not made.

"I was the seventh," they say, and the words land like a stone dropped into still water. "She did not have nine rooms then. She had three, and a different key, and a different bowl. I finished the rooms. I came back to the bowl. And when I understood what it was asking, I could not leave."

The hum in the walls seems louder now, or perhaps you are simply more aware of it, the way you become aware of a sound that has always been there once someone names the silence it fills. Cassiel's hand rests on the railing, and the black glass beneath their fingers is warm — you can see the heat shimmer faintly, a distortion in the air, as though the tower recognizes their touch the way a dog recognizes its keeper's hand. You want to ask what the bowl asked of them, what it cost to stay, whether they chose this or were chosen.

Instead you say, "You're not a servant."

"No," Cassiel agrees, and something moves across their face that is not quite a smile — more like the memory of one, the place where a smile used to live. "I am what comes after the rooms. I am what she is teaching you to become, or what I was, before I gave the rest of myself to the bowl." They release the railing.

"The eighth could not bear what the rooms showed him. He took the bowl first because he thought it would make him strong enough. It did not — it took the part of him that could have understood, and left the rest. She sent him away because there was nothing left to teach."

They turn again, upward, and this time you let them go. You stand on the landing with the key burning cold against your thigh and the taste of copper in your mouth — the same copper taste that fills Yrenne's workroom, that has filled it for as long as you can remember. The fourth floor is two flights below. The east corridor waits. And you understand now, in the way you understand weather, that the question is not whether the rooms will change you but whether there will be enough of you left afterward to be changed.
