Space was not a living thing. Sure, there were living planets, and items, and rocks, and wind, and ghosts, and projections, and many more of such unexpected examples, but Lex had yet to encounter 'living space'. Even so, his presence had an effect on space akin to causing space to groan.
For some reason, he was heavier for the space around him even though he was far from the strongest being inside the Inn. Being affected by the Primordial tribulation had made him something more solid or distinct than everyone else for reasons Lex could not comprehend.
It had nothing to do with power, and yet the consequences were very real. Perhaps Lex would understand this much later. After all, Eclipse would have mentioned the exact reason for it if she had thought Lex could handle it - after all, she had been very open about sharing other random bits of information with him.
