Using her companions as hostages, Reiss forces Lara to lead him to the Cradle of Life. At the crater, they encounter the Shadow Guardians, humanoid creatures that appear in and out of wet patches on dead trees. The creatures kill most of Reiss' men. Lara manages to find the "key hole" and drops the Orb in it. The Guardians disintegrate and the entrance to the Cradle of Life opens.
