Stella was one of the Waneshi who attempted to absorb the power of the Starborn. After her death, she managed to contact Vicki Pallister when they went to London in the 20th century. This was supposed to be a way to get Vicki to not go into the TARDIS in order to stop her own death. However, despite her efforts to convince Vicki that she was the future Vicki, Vicki realised that Stella was an impostor because she would never have reacted the way Stella narrated in her tale, as well as occasions where Stella referred to "Vicki" or "three" in cases where it was meant to just be Vicki and a local friend present.
