S1, E3: Now the NEXO-Knights get rolling in The Fortrex, their own Rolling Castle! This great new headquarters which houses Merlok 2.0 as an operating system, will be how the knights move around Knightonia and protect it from Jestro and his monsters. Speaking of the evil jester, Jestro uses some newly-made monsters to attack a town far from the capitol where he thinks he’s safe from the Knights’ reach. We see two parallel stories here: the Knights training, learning more about digital magic and getting organized as a team and at the same time we see Jestro making monsters, trying to learn how his powers work and talking to the Book. In the end, the Knights roll up in their castle and defeat Jestro and his marauding monsters.
