The grounded sovereign

Prince Kaelen is born into the center of a powerful kingdom, where he is expected to engage in the endless political schemes of his royal brothers. Feeling entirely disconnected from the intrigue of the throne and the hollow weight of nobility, Kaelen makes the radical choice to abandon his life of privilege. Adopting the pseudonym "Kai," he enlists in the brutal, remote Iron-Garrison, stripping away his royal identity to prove his worth on his own terms. It is within this crucible—under the eye of a merciless drill sergeant—that Kai’s path diverges from the mundane. He begins to see the world not just as a martial landscape, but as a series of interconnected systems and energy pathways. — Description from novelcodex.org
