The Concubine's Easter Celebration (слэш)

Gabriel had always felt fondly towards Niall and would do anything it took to protect him from harm. Which is why when a foreign concubine arrives with the same blond hair and is less than nice, Gabriel is determined to try and make things better for his friend. Perhaps Easter would be the perfect time to learn a little more of the former slave's past? At very least, it's an excuse to enjoy some time with the prince and his other concubines. And if embracing their homosexuality was the perfect revenge against a homophobic idiot, then so be it.
