the Holy See to help deal with a recently-translated text called the
Veritas, that causes readers to end their own lives. The Doctor takes
Bill and Nardole to a secret library inside the Vatican. They find
that a translation of the Veritas has been emailed to CERN. Bill and
Nardole discover a portal leading to a hub of other portals, linked to
CERN and the White House, among other places. Meanwhile, the Doctor

read Veritas, but is forced to flee into a second portal with the
translation when the skeletal, corpse-like Monks appear. He is unable
to read the Veritas before again losing his sight. Extremis (Doctor Who) Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
