Sapphire's floor and walls were a soft blue colour with paint going over the walls in stripes of flesh pink and they felt soft and squishy, making it safe for if anyone fell over while inside of her. As for the air, every minite Sapphire would take in some air for everyone inside her. "Everything inside me is powered by my own power, I use my fire conductor in my throat which is connected by a thermo-reactor, which was installed. I used to have it checked every month so that I would be able to provide heat and energy to every partof my body."
