Cepheus (Celestial Spirit)

Cepheus is one of Mako's Gold keys. It was given to her on her 16th birthday by a young woman who was her mother's sister.

History
Cepheus had a dark past. His wife betrayed him and his only daughter turned out to be a Celestial Spirit. When the Celestial King also stated that he was a Celestial Spirit, he wanted to kill himself and reject to that statementabout him. Mako's aunt saved him from that cause by making a contract with him. Cepheus said to her that he will not bow down to some peasent woman and Mako's aunt replied by saying "I will not make you bow down to me. That is not the wa of the contract." Which touched his heart and he began to trust in her. When he was given away to Mako on her 16th birthday, Cepheus swore to Mako's aunt that he'll protect her from anything (Mako is the only niece she'll have and love).
