Everyone has secrets, but some secrets are too big to be kept under wraps forever. One such secret is tired of being mistreated and decides to enact their own sort of revenge, though their motives are far from clear. As events in Arthdal start to spin out of control, it's clear to see that the world needs a savior — or three.
EPISODE 7 RECAP
In the Fortress of Fire, Tanya escapes the fighting and finds herself in a tower room that perfectly matches Eunseom's description of a dream he once had. There is a mirror on the wall and a bell on the floor, and when she picks up the bell, Tanya sees someone peeking at her from behind a curtain — someone who looks exactly like Eunseom.
Dalsae and another Wahan man, Buksoe, also escape the fighting and climb over the wall, only to run directly into Eunseom himself. They're cornered by Yangcha, Tagon's masked warrior, and Eunseom tells Dalsae and Buksoe to run. He nimbly dodges Yangcha's chain whip, managing to get close enough to slice Yangcha's mask before escaping.
Tanya slowly approaches the man in the tower to get a closer look. He avoids her eyes, but he doesn't pull away when she reaches out to touch his lips, and the color he's wearing to hide their purple tint comes off. "Who are you?" she asks tentatively.
In the main part of the fortress, Danbyeok's men finally subdue Asa Ron. As he's led out, he asks Tagon and Danbyeok if they're prepared for the consequences of this. Tagon thanks his brother, but Danbyeok says he only did what's right as a loyal son.
Mihol successfully escapes and makes his way to the bronze workshop, where he picks up a sword and uses it to kill the smiths. He leaves two alive, a man and a boy of his own Hae tribe, and tells them to escape. He reminds them that the Hae tribe traveled to Arth from a far land called Remus, and stayed because of "the fingers" — an engraving on the Great Gochiju rock.
He continues that a mysterious civilization using the same engraving on their shield has turned their homeland of Remus into ruins, and that he believes Arthdal is somehow connected. He tells them to remember that mission wherever they go, then sends them away with the admonition to survive no matter what.
After they flee, Mihol takes several hides marked with instructions on bronze-working from the table and throws them into the fire. Tagon and his men burst in seconds later, but it's too late to save the writings. Mihol says that he's the only one left in Arthdal who knows how to work bronze, but Tagon says that all he had to do was beg Taealha for his life.
Yeolson(who was an inventor in Iark) is captured and brought to the bronzeworks, where he asks incredulously if they're melting stones in the forge. Tagon is impressed that a dujeumsaeng figured out even that much. Yeolson kneels for a closer look, and immediately works out how the bellows fans the flames to make them burn hot enough.
Tagon leaves orders to allow Yeolson to watch the whole process. He goes back to the fortress where most of the remaining Wahans have been caught, but he grows concerned to see that the door to Saya's tower is open. One of his men has gotten to the tower first, and he sees Saya's purple lips that mark him an Igutu.
Tagon walks in, and Saya calls him "Father." Tagon curses and kills his own warrior, then throttles Saya, asking angrily, "How many of my brothers must I kill because of you?!" He lets go, knocks out Tanya, and carries her out of the tower.
Meanwhile, Eunseom is captured with Yangcha's whip chains, which lasso his hands and neck then pull him into the air. With a scream, Eunseom wrenches the chains holding his arms from the warriors, then he swings up and over the pole he's hanging from, landing near Yangcha and slicing his mask off.
