The Call Of The Kingdoms

Three castles, one kingdom. Now, as crazy as this sounds, the kingdom is run by a set of triplets, who needed to come to an agreement.
When their parents died, Reyna, Alexander, and Ember were lost. They knew ruling the kingdom would start with the first born male, but nobody was sure if he was ready.
Having said that, they looked into the rules of royalty.
Alexander wasn't perfect, neither was Reyna nor Ember, but while their age was coming they searched for a way all three of them can rule in unity.
Their day was coming, and their birthday was just around the corner. They would need to find a direction fast.
Of course, finding a sorceress seemed like the smartest thing to do.
But what happens when this agreement falls downhill?
