What is the importance of Saguria in the novel, Endling #1: The Last?

Saguria is the capital city of Nedarra, which is ruled by the Murdano. It is here that the group is betrayed by Luca and taken to the Murdano himself. It is also revealed that the leader is much younger than Byx imagined and has dreams of invading Dreyland even though others, like Araktik, think it is a foolish decision. The group leaves Saguria followed by the Pale Guard on a mission to capture the rest of the dairnes, but manage to escape capture by forcing the Pale Guard to fight the Knight of the Flame outside of the city.
