The twins came home from a run they were trying to take every day. Sophie had a vision that they needed to be out a little longer than normal, but had an urge to ignore it. She didn't though, since ignoring her visions could hurt. So by the time they got home, both of the older siblings were in the temple. The gems were worried and tried to keep the kids from the door, but Sophie ran passed her guardians and held her hand to the door. The blue gem in the star lit up and a snowflake appeared on the door and the center became a hole into a white snow-scape. Sophie stepped through the hole and into Sapphire's room. Robbie ran to the door but couldn't make it before it closed. He put his hand to the door and nothing happened, so he kept trying, and eventually, the red stone lit and the door melted away as fire rose from the floor. He ducked through the opening and soon, he too, was gone. The gems were flabbergasted, but soon Steven popped out of the brightly lit door. They sat and waited for the others to come out.

Inside the temple, Sophie drudged through the snow leaning oddly to the left. She walked for what felt like hours in the vast nothingness, glad that the cold did not affect her as much. There were no trees, no stones, no rivers, nothing you would find in a livable area. It also seemed infinite, which made sense since she was inside the temple. As she walked though, the temperature got warmer, only marginally at first, but eventually, it became warm enough that she didn't have to summon warmer clothes. The snow started to thin out, and she was quickly walking through mere inches on a stony or frozen surface. She soon came to a patch of grass in the snow and a clear wall, that bordered a desert.

Robbie found himself in a similar situation, but on the desert side, listing right. He too walked for hours in the barren land. No cacti or rocks jutted out of the sand, there was no water to be seen. which alarmed him a little as he was getting thirsty, but he kept going. The sheer vastness of the room began to confuse him, until he remembered he was in the temple and the magics there could warp reality. At least the heat wasn't bothering him, just the dryness of his location. In fact it was starting to cool off, and before long he had summoned a light jacket. He eventually joins his sister at the oasis, running full bore into the barrier before ever realizing it was there.

Thankfully sound could pass through the wall, as Sophie explains her experience to her dizzy twin. They start feeling along the wall hoping to find the top or a door, and their gems ended up on top of each other's. A deep reddish purple light radiated from their touched gems and soon they were holding hands, the wall rapidly retreating in a faint glow. The grassy patch underneath them grew to replace the previous two rooms, and became a lush jungle, with a lake. A few trees formed a grotto, but instead of more jungle there was a door, that looked like it went into the burning room. A voice rang out. Calling to them leading them to the edge of a cave by the lake. A screen came up out of nowhere, possibly gem technology, with an image of Garnet on it.

"Sophia, Robert, I'm glad you were able to make it here, I know you haven't fused yet, not properly, but your closeness allowed you access to my, our sanctuary. This room is a near perfect replica of the jungle that Ruby and Sapphire found themselves in when they first met. That's a story for another day, this recording, the device is in the rock directly below the screen, will tell you on your next birthday. But if you've made it here, you're close to the day you'll fuse, it's very close. It's not for a good thing either, bad things are coming, please double up on whatever training videos you can, you and your siblings will need it. I wish i could hug you two right now, and I know that when you see this you'll want to too. I'm leaving training videos specific to you and your fusion, in here, feel free to visit often. But you have to leave, go through the door to the burning room and leave back into the temple, this room does not exit directly into the temple, I helped program the room this way. Go now, everyone is worried."

The two did as their mother told and left through the burning room. Once in the house, they were quickly pummeled by their family. Enveloped in a very tight Spinel hug, the Twins listened to what happened while they were out, Steven and Page told the stories of what happened in their rooms, Page saying she was trained by her mother for a few hours on how to use her gem storage, and Steven explaining how the room makes stuff out of clouds. The twins explained that their moms' room were opposites and desolate places with a small oasis on one side, there was a door to the burning room. They felt no need to explain that garnet had a room or that it wasn't the burning room itself, just yet. It was late and so everyone ate a meal together and the kids all went to bed.
