The biologist descends the Tower's wall
On the twelfth expedition into Area X, four unnamed women (biologist, anthropologist, surveyor, psychologist) find an unmapped structure sinking into the ground that the biologist insists on calling a 'tower'. On its spiral wall, words from a sermon-like text ('Where lies the strangling fruit...') are written in living fungal organisms. Inhaling spores from those words infects her and changes her perception. The psychologist turns out to have been controlling the team through hypnotic suggestion. Among the hundreds of journals in the lighthouse, the biologist finds her dead husband's journal from the previous expedition, and she ends by choosing to go deeper into Area X rather than return.
