The further Orion ventured into the depths of the cavern, an ominous pressure began to mount upon his chest. It wasn't a physical weight but an ethereal presence that seemed to manifest as an intense, almost suffocating force. The air thickened, constricting around him like an unseen vice. Every breath was a struggle as if the shadows themselves were pressing against him, trying to snuff out the very essence of his presence.
The pressure on his chest felt like a manifestation of the labyrinth's will, an intangible force that sought to challenge him beyond the physical and into the realms of the psychological. The air thickened with an inexplicable malevolence as if the very essence of the labyrinth were attempting to intimidate him, to test his mettle beyond mere physical combat.
