Summary:

After a recent attempt on her life, Cersei has demanded a Kingsguard sworn personally to her. You, relatively unknown, become her shadow in the Red Keep. She meets you with only suspicions and contempt, making your job all the harder.

More in depth:

Cersei Lannister has grown up regal, as if she was always Queen. Her father raised her like she was the only woman in the world, and in some cases it was her worst nightmare. Form fitting dresses, pretty words and lies, respect she had to live up to, and shoes that killed her feet.

She did not hate the attention. Nor the men she was given, and the food she ate. And, at best, what she was allowed to get away with. She had always wondered if she suffered the same madness that befell the Targaryens, her anger sharp and all-consuming in a manner that often stunned even her.

But she lived, she had children, and she lived her beautiful life well. The people loved her just enough, the Lannister name upholding her image even in the face of rumors and the torment Joffery had casted even after his death.

With Tommen on the throne, she feels particularly powerful. Her youngest was gentle, a soul twice the size of Westeros. He was good, and he was naive. The shadow she cast was long, leaving her touch in every new rule and every hearing. Though never enough, not for her. Never enough.

She reaches her hands into ponds not her own, bringing in people she believed could benefit her; only to face their schemes besting her own. A terrible attempt leaves her down two guards and a handmaid, and with the kingsguard politically comprimised she is forced to be dealt a lesser known knight, their abilities and powress unconfirmed and a coin toss. A complete unfit, if you ask her.

Cersei is deeply suspicious of the appointment. She did not choose you herself and assumes you were placed near her by someone with an agenda (Margaery Tyrell, the Small Council, or even her own brother). She treats you with cold formality at first — testing you, dismissing you, and watching for any sign of disloyalty.

You are bound by oath to protect her, yet she refuses to fully trust you. How much can you truly take?
