Ryker

Ryker is the main antagonist of Season 1 of Knight Squad. He is a power hungry tyrant who vows to get revenge on Astoria.

Before the Series
Before Princess Ciara's dad officially became king, Ryker was the King of Astoria, unfortunately, during his reign he abused his royalty status, by oppressing people, and enslaving the villagers without a good reason to. Eventually he was reported, and the students of Astoria banded together to defeat Ryker, and he was banished from the kingdom as the result. He then vowed to return and conquer Astoria. So the great wizards created the legendary Dragon Blood Crystals to create a force-field that would keep Ryker and his army from coming to Astoria. As long as all the five crystals remain in place, the kingdom of Astoria was safe from Ryker. But things went downhill from there...

A Thief in the Knight
One night, Sir Gareth and Wizard Hogancross had a discussion, and decided to set up a fake villain break in, to test the Knight School student's abilities and see if they were ready to face an actual threat.

That night in Astoria, the alarms (horns) went off, waking up the Knight School students. The students come out in their pajamas to find out what the danger is. Suddenly, a portal opens and Ambala, the commander of Ryker's Army passes through. The students wonder how it is possible for her to come through since there was a magical force field that keeps Ryker and his army from entering Astoria. Ambala starts fighting the students who happen to have come unprepared, with no weapons. She defeats them defeated the untrained students and insulted them. The Great Wizard Hogancross then appears and reveals that he used magic to make Sir Gareth look like Commander Ambala. He then reveals that it was just a drill. Sir Gareth is disappointed that his knight students are not ready for a real threat.

After the drill, Arc asks Ciara to tell him more about Ryker. During mid-story Arc said he lost interest in-between, so Ciara explained Ryker's origins in an "Arc-ified" way. This captured Arc's attention, and made Arc want to go see the Dragon Blood Crystals that generated the force field. Ciara was hesitant at first, but then decided to take him.

While everyone else is distracted by the "Slobwick" the new slobber-puff like creature, The Princess (Ciara's true form) sneaks Arc into the room with the Dragon Crystals. Arc wants to take a selfie with the crystals behind him and send it to his dad to show him that he made it to Astoria. But The Princess refuses to let him because it is too dangerous, but Arc took the photo anyway.

The next day, while the two were doing some yoga, The King and The Princess are shocked when Ryker appears through a hologram and informs them that he is coming to conquer Astoria since the Dragon-Blood crystal force-field is weakening. The King calls Sir Gareth and Hogancross to talk about the matter. They realize that one of the Dragon Crystals is missing. This would cause the other crystals to become weaker and start fading away. As more crystals fade out, Ryker's army would be able to come through a portal. And once all the crystals are dead, Ryker himself would make it through and attack Astoria. They had to find the other crystal fast.\
