The emperor's life was monotonous and besides going from the court to the study, he would only occasionally visit his concubines in the harem.
Although the Concubine Lavanya was the only Noble Concubine and had the most power and say in place of the empty seat of the queen.
Only those in the harem would know that Concubine Lavanya was actually unfavoured.
The emperor never visited her room after her two sons were born and he would never accept her requests for visitation. Even her personal servants would be stopped if they wanted to send a message to the emperor.
There was no resentment but a simple lack of feelings and it has been like that for many years. Many speculate that if the emperor filled the queen seat, the Noble Concubine would be the first to bear the brunt and be kicked down.
But after many years, there was still no one who could challenge her power, so the harem has been in a state of suspended stalemate.
