When all hopes are gone suddenly Arthur returned to their rescue together with Taliesin's tribe. Arthur screams for Arawn and as Gaius' is about to break the last line of defense Arawn shows up giving hope once more to his comrades and friends. All were enlightened with his return, especially Riannon. Arthur and Gauis had a duel and as he realized that what Arawn wants is not the way of the king but Little King he died in Arthur's hands. His last wishes were to spare his remaining soldier's lives. At the Empire's capital, a figure in white attacks and burns the Imperial Senate to death after revealing to them the death of the Holy Emperor.

As Arawn and Ogam make their way to the source of Gravitas, Arthur and the others continue to hold the upper hand against the enemy. Right as victory seems apparent, an increase in the amount of Gravitas quickly turns the tide of the battle. With things going downhill fast, Ogam prepares to use the Flames of Creation to stop the spell even at the cost of his life. As he does so, Etlym and Dyrnwyn resonate, renewing their strength. Ogam destroys the Obelisk's tip, stopping the flow of Gravitas. As a result, Rathty and Llyr destroy the Cauldron of Rebirth, destroying the Golems, allowing Morgan and Octavia to kill Creon, Mayor of Londinium, and a servant of the White Spirits. Drwc is killed by Arthur, and the group reunite at the Palladium's top, the Garden of the Sky. There they are shocked to see the Emperor's corpse, and Arawn is horrified to see the Angel Lector before them.

Merkadis fires the Electrum Cannon and destroys a mountain. It then uses tentacles to scatter the army, but Arawn, Arthur and the others meet up. Ogam reveals that the only way to stop Merkadis is to use the Power of Words, but the only one who can do it is Riannon. Arawn and Arthur buy time for Riannon to remember the Words of Power; they succeed in cutting several tentacles but are unable to damage Merkadis' main body. Arawn is nearly killed by a shot from the Electrum Cannon, but seeing Pwyll in Arthur encourages him. Riannon remembers the Power of Words with help from Primula and uses it to cripple Merkadis and expose the Angel Lector who begs the Creator Watos for help before he is killed by Arthur. Later in Avalon, Pwyll tells Arawn that Arthur must now become Elf-King of Albion as Arthur Pendragon. Arthur becomes Elf-King of Albion. Limwris tells Ermin to continue writing their stories; Rathty comforts Llyr and forges a commemorative medal for Albion's rebirth. Taliesin and Epona continue their love/hate relationship, and Ogam reveals the Brigantes Prophesy's truth; Taliesin will be an errand boy for the Dragon he befriended for the rest of his life. Arawn leaves his sword at Myrddyn's memorial, and Rhiannon thanks the Morning Star for his guidance.
