The air changed the moment Lara and Lucian stepped down.
It was like crossing an invisible line where the world above stopped existing and another one started.
The staircase went down in a tight spiral.
Lucian went first with the dagger in his right hand and his left grazing the wall so he wouldn't lose balance.
Lara followed two steps behind, with a hand resting on his back to not lose him in the dark.
The Sister with the surgical tray couldn't be heard anymore.
"Do you feel her?" Lucian whispered without stopping.
"She turned right a minute ago," Lara answered. "She's calm, she doesn't know we are here."
They reached the bottom.
Basement Level 1 was a long and wide corridor, with black stone arches holding a low ceiling.
On both sides of the corridor there were wood doors reinforced with iron.
Twelve in total, six per side.
Lucian got close to the first door and pressed his ear against it.
Nothing.
