Astro-Knights Island is the ninth island on Poptropica. The princess of the Kingdom of Arturus has been kidnapped by an evil inventor named Mordred (now under the alias of The Binary Bard), and taken some faraway place in space. The player must build and customize a space vessel and fly among the stars on an intergalactic quest to rescue her and save the kingdom of Arturus. Along the way, the player will visit several planets in his quest and fight a variety of mechanical beasts. The island contains numerous allusions to Arthurian legend, such as the kingdom being named "Arturus", three knights being named Cador, Peleas, and Gawain, and the villain's name being Mordred. The island was in June 2009. This was the first Island where Early Access was available.
