Celation

The Master of Celation (or Celation) was a Galactic Council delegate in 4000.

Celation was a sentient nebula capable of both taking humanoid form and splitting itself apart, letting its pieces take forms of their own. When it did take human form, it was indecisive, often changing the form it took. (AUDIO: The Perfect Prisoners) It had taken both the form of a bald male humanoid (TV: The Daleks' Master Plan) and a female. (AUDIO: The Perfect Prisoners)

Celation had apparently been persuaded to join the alliance by Zephon. When Zephon attempted to leave the alliance, he expected wrongly that Celation and Beaus would join him. Along with Trantis and Mavic Chen, he was one of the most powerful leaders of the alliance.

The execution of Trantis ensured Celation's loyalty to the Daleks, but his jealousy and rivalry with Chen led to the end of the alliance. He became the most forceful opponent of Chen, demanding his expulsion from the Council, but after they were betrayed by the Daleks, he planned with Chen, Beaus and Malpha to form a new Galactic Council. He agreed to return to his own people and warn them about the Daleks' invasion plans and help fight them, if Steven Taylor and Sara Kingdom would free them. (TV: The Daleks' Master Plan)
