The Service Beyond Death Ending is an ending in Prisoners of the Elder One. It involves leaving through the golden doors with a fully restored Tiffany and a 'romanced' Valda. This requires the Transfigurative Orb used on Aya while in the Nexus, and informing Valda about the attempt on her life.
Erik wakes up in his bed, assuming the prior events to be a dream. Later on, however, Valda shows up at his door, claiming that after Erik and Tiffany left, she asked the Elder One if she could live with Erik in exchange for her magic. They retreat to Erik's room, but are interrupted by the Elder One, who punishes Valda for attempting to use magic on Erik to make him immortal. She is put in a servant's outfit, and made to obey any and every order Erik commands of her.
