Ritual fails as spiders emerge

Barnes and Mike’s futile mandala ceremony spirals into chaos when their incantations fail to control the unseen forces. As the chanting reaches a frenzied pitch, the earthly rules of the cellar dissolve, warping at the edges where mathematics falters and dimensions groan. Two colossal spiders materialize in the hidden corner of the room, their grotesque forms pulsing with unnatural light. The first breach shatters the fragile safety the companions once relied on—a warning that the invasion has begun in earnest, crossing from the metaphysical into the physical. Barnes and Mike’s panic underscores their fatal misunderstanding of the crystals’ true power, while the Doctor and Sarah must now confront the reality that their enemies have begun their move in earnest, with no time left for caution. key_dialogue: [ BARNES: It's not working!
