Estinee
From Tardis Wiki, the free Doctor Who reference
Estinee was the last of the Destrans following the Kotturuh judgment of her home-world. She survived due to having an immunity to death.
She appeared to be around fifteen years old, with sharp and thin features and yellow skin. Her eyes were owl-like and her hair was wild green like seagrass. She wore a Lifeshroud bodysuit, believing that it was keeping her from death by the Kotturuh's "gift".
She first encountered the Doctor on Andalia in the dark times. (PROSE: The Knight, The Fool and The Dead)
