This ritual is contained in the reassembled Winds
Unknown to Adad. It must be performed within one
cable of the Father of War.

A cable is a standardized
Assyrian distance equal to 720 cubits, 373.4 meters,
or 1,225.2 feet.

Once the ritual begins, the Father of
War cannot approach, retreat from, or interfere with
the operators. The Sons of War may do so at their will,
motivated by fear of the obsidian chips inside them.
The chips cannot attack the operators of the ritual,
but they can attack the Sons who carry them.

The ritual involves long, chanted exhortations
in Akkadian, Aramaic, and Sumerian. The operator
need not understand those languages. Mastering the
ritual means learning them by rote if necessary. To an
operator who can understand them, the gist of the
chants is that:

“Shagash, the god of slaughter, the Father
of War, has been satiated by bloodshed and now must
leave in peace; that holy Enlil sends cleansing winds
and storms to drive the god of slaughter away, and
smashes the sharp blades with his mattock; that Inanna,
the Queen of Heaven, goddess of war and love,
decrees that war is over and demands that the god of
slaughter depart; that her brother Utu, the sun, the
god of justice, shines down upon the god of slaughter
and compels him to depart”

and so on. All that is
mixed with imprecations and abjurations in older languages
that no human scholar could identify because
they formed in tongues older than humanity.

While singing, the operator places on the ground
statues that represent the Sumerian gods Enlil, Inanna,
and Utu. The statues can be small, and they can be
simple or even childlike. No particular skill is required.

The operator, chanting, inscribes sigils in the stone or
earth. Scholars of ancient languages would recognize
some as Akkadian pleas for the Father of War to depart.
Scholars of older wisdom might recognize others
as versions of the Elder Sign.

The ceremony culminates with the breaking of
weapons. The description of the weapons to break is
unclear. If the operator chooses to break an obsidian
knife, or a bronze sword, or smash an AK-47 with
sledgehammers until it is inoperable, that satisfies
the ritual. The obsidian chips that make up the mass
of the Father of War collapse to the ground, inanimate.
It remains banished until someone summons
it again with Call Forth Those From Outside.

It is clear in the compiled texts that even if the
Father is banished via the Closing of the Breach
ritual, it can return immediately through the Throne
of Blood. The way to block its return is to seal the
Throne of Blood with its Elder Sign stopper before
banishing the Father of War. Once that is done, the
Father cannot return.
