Mu-deok wakes freed of the bells as Jin Mu predicts her end, while a voice tells Uk, the King's Star, that this is not his end.
The Cheonbugwan Gwanju warns Jinyowon may lose its relics and, as her brother, tells Lady Jin to name Bu-yeon heir at the Unanimous Assembly.
Uk calls the grotesque a fiction, but Jin Mu argues people will think he still cares for Naksu, and Uk vows to catch her himself.
The schemer explains how a Naksu who does not exist will haunt Uk forever and split him from Jin Bu-yeon and Jinyowon.
Jin Mu reveals he wants the fire bird and tells the Crown Prince their pact only ends if he confesses to Uk how Naksu was used and killed.
Jin Mu claims the deaths settle the matter; the Crown Prince insists he must find a cure for Yul or Jang Uk will never back down.
Officials shout that Jin Mu must sacrifice himself to prevent a war; the only hope left is Lady Jin of Jinyowon.
The Gwanju begs Lady Jin for a cure; she mocks his fear of Jang Uk, and he threatens to drag Jinyowon down with him.
Jin Mu apologises at the gate, but Uk's real target was Lady Jin; he begs her for Yul's life and tells Jin Mu killing him is not the priority.
After the standoff ends, Uk tells the Gwanju his own life hangs on whether Yul survives.
Jin Mu reveals Uk is the late king's son with the King's Star and the Gold Plaque, and asks leave to send him far away.
The Crown Prince says Uk fights only to protect others; Jin Mu calls that weakness and dismisses the missing turtle.
Bird-shaped earthenware panics the capital; Jin Mu admits he dumped it and plans to plant more in the canals with the Crown Prince's help.
Jin Mu tells Ho-gyeong another family will dance at the lake's rite; she refuses Jinyowon's artifacts and invokes the plaque.
Jin Mu and the Crown Prince charge Ho-gyeong with letting Songrim near the fire bird and point to her graying hair as proof she has weakened.
Bu-yeon arrives with the plaque, refuses to surrender it, and offers to prove her returning divine powers to Jin Mu.
Jin Mu throws the plaque into the sorcerers' prison Gwido; despite Ho-gyeong's fear of the wraiths, Bu-yeon promises to bring it back.
At the secret gathering of soul shifters, Go Won questions what happens to those who lose their bodies, then declares he stands with Jang Uk.
Uk traps the secret room in a barrier and fights every soul shifter, telling Jin Mu he came to do what is right, not for revenge.
In Gwido, Jin Mu thinks Bu-yeon will help him claim an ice stone, but it drains him instead, and he realises who she really is.
The Queen finds a dying Jin Mu in Gwido, learns the last Soul Ejector is in her own blood and that he shifted her soul; he plans to leave in a new body.
The King asks whether Jin Mu still lives and is told he is looking at him; Jin Mu offers to share the ice stone's power forever.
Go Won learns a soul shifter in the palace is Jin Mu; the King sides with him and takes away the Crown Prince's Gold Plaque.
The Assembly's mages force their way in; Jin Mu drains Jin Ho-gyeong until Cho-yeon opens the door, and Jinyowon starts to collapse.
Jin Mu and the King offer Park Jin the power to save Maid Kim; he admits he wants it, then vows to stop them anyway.
As the mages hesitate, Uk wakes the fire bird himself and turns their own creed of power for the powerful back on them.
