Tameri was an orphaned puppy adopted by Taliesin dir Rhiannon and Sky Rhiannon into Cercatori d'Arte, and given the Rhiannon name. Due to her black fur color, her schizophrenic stepbrother Liam finally snapped and murdered her, earning his banishment from the pack. Tameri's ghost remained, attaching to her newborn brother Myrddin dir Rhiannon and becoming his invisible playmate after his mother and siblings departed. As a spirit, she has retained her puppy innocence and likes to play with those who can sense or see her.
