Lind's room was partially cannibalized after half a year of experiments with the dimensional pocket. He had been happy to see how easy it was to make a portable space early on but entering it was impossible when tied to his spirit!
He tried tying it to his body but that failed miserably as well. It actually seemed to become corporeal when he tried and shattered half the furniture!
It also was just as fragile without being connected to his harmony. Even with layering the elements as he had seen occur with his harmony in the mix, its fragility was not so easily fixed with the elemental arrays!
It took him some further experiments to grasp it was his spirit that gave the previous strength he felt!
He then just tried to create an anchored pocket dimension and learned a great deal. With his Law Eyes, he saw tendrils of Qi latch outward into the very essence of the air and earth. It literally drew its power from Heaven and Earth!
