The sewers were a maze of dark, damp tunnels, and the stench was overwhelming. The team moved cautiously, their torches cutting through the darkness as they navigated the labyrinthine passages. Lyle kept his senses alert, his enhanced hearing and night vision allowing him to detect faint sounds and movements that others might miss.
Even though all the people present were at the very least high-grade Tier III combatants whose eyesight and hearing were incredible, allowing them to even see through the darkness without needing to use a torch, Lyle was above them in that regard.
They were using torches simply because there was a chance they would miss something as they didn't have real night vision like Lyle did.
