Galyari

The Galyari were a species who had a deep fear of the Doctor, referring to him as "the Sandman".

Biology
The Galyari were eight feet tall. (AUDIO: Dreamtime) They had extraordinary eyesight. Because of this, they found intense colour combinations, such at the Doctor's coat, painful. In the past, they had a chameleon-like ability to blend in with their surroundings. (AUDIO: The Sandman) Their skin was photoreflective. (PROSE: Grey's Anatomy)

Culture
The Galyari performed a production of Macbeth on Berkoff IV. (AUDIO: The Crystal of Cantus) Irving Braxiatel believed that the Galyari would get involved in any conflict. (PROSE: Parallel Lives)

Technology
They stored their knowledge in the "Shushkubra", memory eggs which were grown aboard the Clutch from discarded Galyari skins. (AUDIO: The Sandman)

History
The Galyari were seen as a credible threat to the Braxiatel Collection. (PROSE: Parallel Lives)

Alternate universes
In an alternate universe where the Time Lords sold their technologies to other races, the Galyari received the Oubliette of Eternity from them. (AUDIO: Reborn)
