The House of Hades is a special visitable location accessible via certain story events branching from Tartarus. Unlike standard dungeon areas, it functions as a narrative hub where Melinoe encounters characters from the original Hades — including Zagreus, Hypnos, Dusa, and others.

Visits are triggered by specific story milestones and Incantation completions rather than by a standard run route. No combat occurs here.

The House of Hades serves as a bridge between the two games' narratives, allowing Melinoe to learn about events after the end of Hades 1 and receive guidance from her family. Interactions here often unlock new Incantations or advance relationship storylines.

• Cannot be visited freely; requires specific trigger conditions
