Okay kiddo, so the Vigil of the Princes is like a story about kings and queens. Imagine a big castle with lots of rulers living inside. These rulers are called princes and they are very important because they help make big decisions for their castle and their people.
Now, every year the princes have a special gathering where they stay up all night to talk about important things they need to do for their castle. This is called the Vigil of the Princes.
During the Vigil, each prince takes turns talking about what they think is important for their castle. They also listen to each other, so they can all work together to make good decisions.
At the end of the Vigil, they all have a big celebration because they were able to work together and make good plans for their castle.
So, the Vigil of the Princes is like a big sleepover where they talk about being good leaders and working together to make their home a better place.
