In Opening Knight, The King mentions that Astoria is currently fighting one of their worst villains, Ryker, and his army. The King's oldest daughter has been leading the battle. It is also revealed that The Princess of Astoria, lives a secret double life where she transforms into Ciara, a knight in training.
In Knight in Shining Armor Day, Astoria celebrates Armor Day, a public holiday to commemorates the magical Armor of Astoria made to protect Astoria from its enemies. The Armor of Astoria was made by the greatest wizards at the order of the first King of Astoria; but it got lost in an attempt to hide it from their enemies. Armor Day celebrates the hope that one day, the armor will be found again.
In One Magical Knight, it is revealed that Astoria has a Magical School called Spitzalot School of Sorcery where everyone with magical powers is forced to attend in order to learn how to use magic.

In Tonight, Two Knight, Astoria's Army, "The Wolf Platoon" returns early from their battle against Ryker's Army.

Ciara later sneaks in to read the scroll and finds a secret message from Princess Eliza, saying that she is on a secret mission to recover the Armor of Astoria.
In A Knight's Tail, Astoria celebrates the annual Astorian Fish Gut Grab Festival to bring good luck to their fishing season. Part of the ceremony involves the king grabbing a worm from a tub of disgusting fish guts.
