Space
When he saw the familiar vortex appear in the empty space in front of him, Emery felt an electric sensation coursing through his body. He was overjoyed to see that he could open his storage room once again.
Then after that, his mind drifted to the many items he had left in the storage space; the weapons, potions, and other valuables.
To his surprise, when he took a look inside, he found that the space within was much more spacious than in his memories. Even the gate which was the entrance to the space was wide enough for his body to walk through.
Intrigued by the new find, Emery quickly stepped inside and found himself in a familiar-looking dark space, but now it seemed to have become three times bigger than the last time he came. The discrepancy between what he saw and what he remembered made him question his memories of the place.
