The Velvet Room often manifests itself differently in the game, but it is always covered in blue velvet and hosted by Igor. The purpose of The Velvet Room is always to manage Personae. The room is invisible to all except those with high spiritual sensitivity. In Persona 3, Persona 3: FES, and Persona 4, the room is inaccessible to those who are not chosen. The Velvet Room has a distinct music theme titled "Poem of Everyone's Soul" (全ての人の魂の詩, Subete-no hito-no dama-no shi), also known in English as "Aria of the Soul".
The method of summoning demons in the Velvet Room significantly change between Persona to Persona 2 and Persona 3 to Persona 4. For the first two games, Igor offers the cards to power his evil phone and call the realm of unconsciousness. He listens to a sad story from the other end which makes him cry, and the flood of emotion coupled with the power of the cards open a dimensional rift that summons the Persona. For the latter 2, Igor performs an arcane ritual that fuses a certain number of Personae cards together to create a new one, which summons a Persona within the protagonist's soul.
