Jabe

Appearing at the End of the World Party, along with several other of her kind, Jabe was a representative of the Forest of Cheem, a race of humanoid trees, who had originally spawned from Earth, and were paying homage to their dying birthworld. Upon meeting the Doctor, she took an immediate interest in him, and, after discovering his true heritage, felt grief at the loss of an entire species, with he as the only survivor. When Platform One came under attack, she sacrificed her life valiantly, staying behind to allow the Doctor to fix the sun filters. She burnt to death under the immense heat.
