Benelisan

From Tardis Wiki, the free Doctor Who reference

The Benelisans were natives of Benelisa. Their civilisation dated back billions of years, but their population was very low. Their technology was based on crystallography.

Centuries ago, the Beast travelled to Benelisa and fed on the natives, accidentally wiping them all out. Before they became extinct, the Benelisans sent Azoth to locate and destroy the Beast. (PROSE: The Taint)
