The blindfold had a strange fragrance that kept filling Lorenzo's nostrils. It wasn't exactly overwhelming, but it did disorient his sense of direction.
With the sensory abilities of a Demon Hunter, coupled with Lorenzo's extraordinary memory, even blindfolded, Lorenzo could gradually retrace the route he had taken. But clearly, even this was taken into consideration by the Purification Mechanism, leaving Lorenzo no room to maneuver.
All he could hear were the roars of mechanisms, seemingly advancing underground. And indeed, with Old Dunling's complex underground facilities, it was the perfect place to conceal a secret mechanism.
During the time of the Radiant War, many shelters were constructed underground in Old Dunling. They were often connected to the intricate underground waterways, as complex as an anthill. Without a map, it was easy to get lost inside and eventually perish from hunger.
