Mithya's eight worlds - Shyn, Lustr, Sparkl, Glo, Dazl, Shimr, Syntilla, and Glytr - were plunged into darkness when the wicked Shaap Azur captured all the 32 stars of Tara. All seemed lost, until Taranauts Zarpa, Tufan and Zvala - three bright, brave and gifted mithyakins - set out on the difficult and dangerous quest to bring back light and cheer to Mithya. Having set free the four Emeralds of Shyn, the Taranauts are now racing against the dingdial to track down the Sapphires of Lustr. But the wily Shaap Azur has made the challenge tougher than ever - this time, all the riddles are hidden in Lustr's baffling, brain-scrambling Mayazaal! To make things worse, the Demazurs are hot on their trail. Can the Taranauts call upon all their reserves of strength, skills and talent as they battle vicious flowers, weeping trees, vengeful minimits and their own doubts about their mysterious companion, Zubreymunyun.
