Lin Ze investigated the Old Port murder scene, learned from Carl that the cult’s blood was cursed, and questioned Riddle’s Diary about the missing wizards and the vampire Flamel had sealed away. Riddle suspected the cult was feeding the vampire, so Lin Ze sent Ben to search Ministry records for a pure-blood family linked to dark creatures.

• Lin Ze Apparated back to find Ryan dead and told Ben there was no need to notify the other Ministry departments.

• Lin Ze asked about the blood race and the vampire Flamel had sealed, and old Mulciber said the creature had never died.

Lin Ze learned that the Icon Church near Brighton had been destroyed by a ley line shift and received a message that the Holy Lord would appear at Brighton Pier. He led a small team to investigate, where he found Miriam among a gathering of robed figures.

• Lin Ze asked Pick to search the Ministry records and learned that the Icon Church north of Brighton had been destroyed by a ley line shift in 1712.

• Lin Ze and Amos noticed blood-scented fog gathering over the pier and circled toward its thickest point.
• Lin Ze saw dozens of dark-robed people holding candles, with Miriam standing at the front.

Lin Ze and the other wizards interrupted Miriam’s sacrificial ritual at the docks, but the sacrifice summoned a supernatural presence aboard a black boat. As black mist spread across the dock and swallowed the kneeling Muggles, the wizards retreated, leaving the Holy Lord’s arrival underway.

• Lin Ze confirmed that Miriam’s followers were performing a sacrifice and told the wizards to wait before intervening.
• Amos and Barty Crouch Jr. attacked Miriam, but one of her men took both spells as the believers scattered and the dock caught fire.
• Miriam’s knife turned the black sheep into a wounded wizard, and she welcomed Lin Ze and the others as sacrifices for the Holy Lord.
• Blood-red light surged from the six-pointed star as Miriam convulsed, while Barty Crouch Jr.’s spell failed to penetrate the barrier around her.
• A black boat reached the dock, and black mist poured from it, extinguishing flames and freezing the planks as Lin Ze and the other wizards Apparated away.
• The black mist engulfed the kneeling Muggles, who ecstatically repeated that the night embraced them.

Lin Ze and the others confronted Targaryen Nox as he emerged from the black boat and drained Miriam and her followers. Their attacks failed when he absorbed the blood and black mist, leaving him transformed and the group in danger.

• Lin Ze, Barty Crouch Jr., Amos, Mia, and Arthur scattered with Apparition and unleashed a barrage of spells at Targaryen.
• Targaryen absorbed the black mist, the blood in the star formation, and the remaining Muggles, then released a force that crushed all their attacks.

Targaryen transformed into a monstrous, winged creature and battled Lin Ze, Amos, Arthur, and Barty Crouch Jr. at the docks. As the group struggled against his strength and regeneration, Mia unleashed Starfall, bathing Targaryen in blue-white light.

• Amos, Arthur, and Barty Crouch Jr. helped Lin Ze land several blows, but Targaryen rapidly regenerated his injured wing.
• Mia cast Starfall, opening a rift above the dock and pouring blue-white light onto Targaryen as her lips grew pale and veins bulged at her temples.

Lin Ze, Mia, Amos, Arthur, and Barty Crouch Jr. overwhelmed Targaryen after Mia’s Starfall spell wounded him, and Barty burned him to ashes. The star formation then activated, revealing that the Dark Night Society had sacrificed twelve wizards to awaken a primordial vampire sealed beneath the ground.

• Mia struck Targaryen with Starfall, and Lin Ze followed with Dawn, burning away his wings and weakening him.
• Targaryen survived the attacks and unleashed black-mist tentacles, so Lin Ze rescued the exhausted Mia with Apparition.

• Amos hesitated when Targaryen asked to be killed, but Barty Crouch Jr. used Fiendfyre to reduce him to ashes.
• The star formation blazed, the ground trembled, and Lin Ze realized the sacrifice had been meant to awaken a primordial vampire sealed below.

Lin Ze and Barty Crouch Jr. faced a Primordial Vampire emerging from beneath the docks until reinforcements arrived and joined the battle. The wizards’ attacks damaged the monster only briefly, and Lin Ze began casting Dawn as the fight continued.

• A huge Primordial Vampire burst out of the ground, and Lin Ze and Barty Crouch Jr. braced to confront it.
• Amos returned with Moody, Amelia, Ben, and more than twenty wizards from the teams, and Moody organized them into battle positions.
• The Primordial Vampire unleashed black-mist tentacles and a crushing pulse, disrupting the wizards as they countered with fire spells.
• Moody, Barty Crouch Jr., and other Aurors cast Fiendfyre while the vampire’s black mist rapidly repaired its wounds.
• Lin Ze began chanting Dawn, and the goddess’s phantom appeared behind him.

• Lin Ze summoned a phantom goddess to attack the primordial vampire, while Moody and the others supplied him with magic and the Aurors attacked with Fiendfyre.
• The goddess's silver beams exposed the vampire to the Aurors' flames, which burned and disintegrated its body.
• A stone coffin appeared inside the collapsing vampire, and a figure with spikes driven through its joints sat up within it.
• Lin Ze passed out, and his silver badge opened a rift crackling with blue electrical arcs.
• Rodna stepped through the rift, checked that Lin Ze was alive, and looked toward the stone coffin.
