Rain Ceremony

The Doctor identifies the Rain Ceremony as the site for an imminent human sacrifice, where Ian escorts the victim under duress. Barbara, embodying Yetaxa, forbids the ritual outright, wielding divine authority to end bloodshed and reform Aztec ways before Cortés arrives. This unseen space drives the temple clash—its promise of death sharpens Barbara's defiance against the Doctor's pleas for non-interference. Susan's alert on approaching high priests underscores the ritual's urgent pull, blending sacred dread with revolutionary stakes.
