You hear a door open upstairs, followed by footsteps. Your brother comes down from the top of the steps, stopping halfway.

"Did I just hear you yell into the backyard?" He says.

"What backyard?" You reply. He pauses, his expression contorting in confusion.

"What?" He says after a moment.

"It's all void out there, look," You say, pointing to the backyard.

His head turns towards the backdoor, trying to see what you're talking about. He walks down the rest of the steps and approaches the glass door.

"...What the hell?" He says, trying to find the ground.

He opens the glass door and steps onto the porch. He leans over the railing, trying to find something, anything, besides the house and the void.

He reaches into his pocket and pulls out his phone, shining the flashlight over the edge.

You decide to get up and join him. Maybe looking with him will reveal something...?

"How the hell did this happen?" He asks.

"I don't even know how I could know," you reply.
