In Curse Of Strahd, Majesto met The Pack, excited to find a group of people who were allowed to see him. During the Riots Of The Blazing Sun, the imp invisibly assisted Fiona in stirring up the crowd, invisibly knocking torches and attacking guards to create further pandemonium.
An Imp bound to Lady Fiona Wachter after being summoned from the Lower Realms, Majesto spent much of their time invisible to Human eyes. He rarely left the Wachterhaus, as Fiona considered the imp too precious of a resource. Instead, he was e often employed to spy on Fiona's guests as well as her cult members, and assisted her in illusions to establish the "legitimacy" of Fiona's station. Turning invisible, Majesto would move objects around the room or make coins appear, causing the cultists to believe in the power of their demonic chanting.
Despite being limited to the confines of the Wachterhaus, Majesto's impish nature could not always be contained. When he grew bored, he would fly upstairs to mess with the already-insane Stella Wachter by pretending to be a Dog or "another" Cat.
