The Old Argi Beltz Group

The Old Argi Beltz Group
A witness’s memory
Elena Ochoa recalls a commune at Argi Beltz that began with spiritual gatherings and animal sacrifices. She says talk of human sacrifice drove her away.
A recurring location
The old meeting place is now a guarded estate. Its past gives Amaia a possible link between the baby deaths and the people who still visit the property.
The Lesaka Confession

The Lesaka Confession
A protected witness
Sarasola arranges for Amaia to meet a former member of the Lesaka Secret Group. He describes a leader who promised power through offerings and admits that a newborn girl was sacrificed.
The same pattern
The witness remembers a pregnant woman in the Baztán group and a child treated as if she had no name or family bond. Amaia recognizes a possible connection to her own history.
The Leader’s Identity

The Leader’s Identity
A false professional name
The witness remembers Xabier Tabese, a charismatic man who moved between the groups. Records reveal that the respected Madrid clinician called Tabese was Xabier Markina.
A family revelation
Xabier Markina was the judge Markina’s father. The discovery transforms a historical investigation into a present-day crisis involving Amaia’s lover and the father’s surviving network.
Debts That Persist

Debts That Persist
No clean exit
The witness says members cannot simply leave the group: an unpaid sacrificial debt follows them. Even people who abandon the practices remain vulnerable to the cult’s demands.
A pattern of leverage
The claim helps explain why old members prospered, why some later suffered, and why the group continues to control people through fear, guilt, and promised benefits.
The Network Is Exposed

The Network Is Exposed
The hidden remains
At the Tabese family tomb, Amaia sees the missing children and evidence of repeated offerings. The cult’s private ritual space turns rumors and scattered graves into tangible crimes.
Arrests and evasion
Police arrest the lawyers and move against members at Argi Beltz, but Xabier Markina remains at large. The network is struck, not conclusively erased.
