Moriarty’s allies challenged the serpents at several locations, while Violet faced Professor Purlie’s test at the Forbidden Forest bonfire.

• Herpo used mental force to find the five luxury items in the Slytherin Common Room, but Moriarty trapped them in an Alchemy Matrix and tried to seal Herpo inside it.

Moriarty fought Beedle the Bard, whose green book brought figures and creatures from its tales to life and let him create attacks through the Fountain of Fair Fortune.

After Moriarty, Dumbledore, and the newly arrived Grindelwald defeated the Peverell Three Brothers, Grindelwald identified the Black Forest as being in Swabia, Germany.

• Moriarty and Krum arrived at the Phoenix Nest, where Dumbledore gave Moriarty the Fire Mirror and revealed that he had returned to his youthful appearance.

• A young Thunder Dragon warned Ithiel that a Phoenix was approaching, and Ithiel rose from her throne and commanded the thunder.

Moriarty encountered the Giant Dragons guarding Swabia and was pulled into their palace by a powerful woman wielding Thunder Elemental Magic. After proving he was a Slytherin rather than Herpo, he tried to discuss their shared enemy, Larpo, but the woman remained domineering and refused to reveal what she knew.

• Erls stopped at the edge of Swabia, where Dumbledore explained that the lightning marked Giant Dragon territory, and Moriarty decided to approach the dragons himself.
• A lightning-wreathed woman threatened to destroy the Peverell Family, but Moriarty identified himself as a Slytherin and was dragged into her palace.
