" These outcasts are not the only cursed arakkoa holding their ground in Arak. A curious cult has formed in worship of Ka'alu, my consort and the keeper of my brood. They are considered to be quite... odd. Regardless, the outcasts will need their help." — Anzu 
Ravenspeakers, calling themselves the Flock, are an excentric cult of cursed arakkoa that worship Ka'alu the Raven Mother, the consort of Anzu. They are based out of the Nest of the Ravenspeakers in the Spires of Arak and are led by High Ravenspeaker Krikka. They are considered to not be entirely sane, but are nonetheless allies of the  Arakkoa Outcasts.
After fighting off the
Bloodmane tribe of saberon, the Ravenspeakers successfully summon Ka'alu, who then aids the Outcasts in the attack on Windswept Terrace.
The Ravenspeakers frequently reference various scriptures and religious teachings. The
Ravenspeaker Scroll Fragments extol the many virtues of the dread ravens and detail the finer points of the Ravenspeaker beliefs.
High Ravenspeaker Krikka, when all of the flock have gathered the end shall come, and the world will be torn asunder in a great catastrophe. However, Ka'alu will apparently save the Ravenspeakers from the destruction.  The
Parchment of Dust reads "Put the featherless against one another so that our claws remain unsullied!"  The
Writ of Faith says that great doubt will come in time of crisis but one must put their trust in the Raven Mother and all will be as it should.  It was foretold in the
Scroll of Order that upon calling for a sign the Ravenspeakers would receive one within thirty minutes or less.  It was said in the
Journal of the Rising Sun that eating in the mornings cannot be done without harming a few eggs.  It is written in the
Scroll of Sermons to "Bite the claw that strikes you". It is also written in the Scroll that the Raven Mother is not patient.  There is a lesson from the
Scroll of the Dark Dawn that reads "Ravens of the flock should stay together."  It was written in the
Tome of the Falling Sands, "Time waits for no one".  There is apparently a ritual called the "service of the headless fowl".

Some players have speculated that the Ravenspeakers eventually became the
Grishna, an Anzu-worshipping arakkoa cult found in the Blade's Edge Mountains of modern-day Outland.
