Vermine
From Tardis Wiki, the free Doctor Who reference
Vermine were creatures that travelled from another dimension using red light, and possessed anything that was red. They entered N-Space via Bevell's shop in a jigsaw piece. They wanted to invade and conquer the universe. The Doctor trapped them in a mirrored music box. (AUDIO: The Colour of Terror [+]Loading...["The Colour of Terror (audio story)"])
Some of the Vermine escaped through time and merged with the Vashta Nerada to create the Red Darkness. (AUDIO: Red Darkness [+]Loading...["Red Darkness (audio story)"])
