Offered up by her government, Cyreen is given over to an ancient hero to placate him into cooperation. No pressure.
When the Hero of Morcud was betrayed and put in stasis, he demanded that if they were ever to wake him, he needed the woman that they had denied him.
Five hundred years later, his help is needed, and Cyreen is one of three women with the DNA profile that he demanded. As he is still in his stasis tube, she got a good look at all parts exposed by the clear housing. When he sat up and returned her frank gaze, she is taken aback. The two delicate and lovely creatures that also matched his requirements were huddled together and weeping at the thought of the hybrid general touching them. Cyreen was intrigued.
General Xan looks at his options and makes his decision. Cyreen is his, and there is no end date to the contract.
Oh, the things she is willing to do to save her world. She had better make a very long list before he puts some trousers on.
