Story Guide
Episode 1
Clara is dressed and ready to leave for Stormspire to marry the Dragon Prince, sealing an old alliance between tide and flame. Clara is terrified: everyone whispers the prince is a brutal tyrant who executes anyone who defies him. Then Mabel freezes — she has seen a vision of Clara's wedding gown and her sister's death. Since childhood, the priests called her visions a gift from the gods.
Mabel refuses to let the future happen. The covenant only demands a princess of their house, not specifically Clara, so Mabel takes her sister's place. She promises to fight her way out if the marriage fails. One mystery remains: no outsider has ever seen the Dragon Prince's face.

Episode 2
Mabel arrives in Stormspire on her wedding day, only to learn the Dragon Prince won't appear. He's recovering from injuries in the forbidden grounds, so the betrothal has been transferred to Lieutenant Adrian, who will marry her in the prince's place.
Mabel bristles at being treated like a package handed off at the last second, and the court sneers that a minor kingdom should feel honored. Still, she looks Adrian over and decides he's acceptable — on her own terms. "You don't get to assign me to anyone," she makes clear.
After the midnight ceremony, Adrian offers to escort her to her chambers before military duties. A slip of the tongue about "my prince" leaves Mabel suspicious.

Episode 3
Mabel senses Adrian is hiding something, but the welcome feast turns hostile fast. Lydia and the court mock her as a lesser princess marrying beneath Stormspire's dignity, and Mabel fires back that they're simply jealous she's marrying Adrian.
Then Lydia invokes custom: a foreign bride must kneel before the throne and drink three cups of dragonfire wine to prove her sincerity. Mabel agrees to drink but refuses to kneel. The wine burns her, and Lydia pushes for more — demanding she kneel and beg forgiveness or leave Stormspire at once. Mabel stays defiant: she'd rather die than kneel.
Episode 4
Cedric, the Dragon Prince's chief aide, arrives and invokes the crown's authority. By the prince's order, Mabel is to receive full royal honors — no princess has ever been required to kneel or drink dragonfire wine. The ones who humiliated her are taken away.
Mabel suspects Lydia was involved and insists on settling that score herself. Later, Cedric confronts Adrian: if he cares so much, why not save Mabel himself? Adrian refuses to expose his identity yet and claims he simply finds her interesting — though he already gave Cedric his royal token to protect her.
Meanwhile, Lydia reminds Adrian of a promise: tomorrow, as every year, he'll spend the day with her.
Episode 5
The day after the wedding, Mabel learns Adrian is going to Lydia, and her fury explodes. She hurls him to the floor in front of everyone, then flips into a sweet, wounded act — the hurt bride who just couldn't control herself.
Adrian shocks the room by declaring Mabel will come with him tomorrow; as his wife, she has every right to know what this is about. He promises to explain everything once they're alone. Lydia protests that their promise was private, but Adrian holds firm.
Mabel isn't softened. Coming along doesn't put him off the hook — she still wants a divorce.
Episode 6
Adrian finally explains: Lydia and he aren't involved the way Mabel assumes. Tomorrow is the anniversary of Eliza's death — Lydia's father, who died covering the royal families' retreat. Adrian promised to visit the grave with Lydia every year, and now he's bringing Mabel too.
Then he offers something rare: his heart scale, kept close since he came of age, given only to the mate a dragon has chosen. Mabel accepts it — for now — and warns their marriage depends on his behavior.
The tender moment shatters when a lieutenant bursts in: Lydia has left a suicide note and vanished.
Episode 7
On their wedding night, Adrian prepares to chase Lydia's note. Mabel is furious — of all people, why her, tonight? Adrian insists Lydia is Eliza's only daughter and he can't gamble that this is another tantrum. But he won't leave Mabel behind: she's coming with him.
On the old North Road, Mabel finds Lydia herself. Lydia claims Adrian would have married her eventually and only tends Mabel out of debt to her father. Mabel fires back that if Lydia truly loved him, he would have married her already — he chose Mabel instead.
Then Lydia poses a cruel question: if they both fell, whose name would Adrian say first?
Watch how far Mabel will go when Lydia's jealousy turns deadly — and whether Adrian's hidden scales ever come to light.
