In order to defend himself in Lord Sparr's evil underworld, Galen needs the powerful wand of Urik, a magic tool that's been hidden for years. Keeah and her Upper World friends attempt to find the wand by following the Moon Scroll, which has the power to take anyone who reads it back through time.

Eric and his friends seek the truth about a mysterious, magical snowflake from a flying blue serpent, which Ko will stop at nothing to possess.

Ko is back in power -- and nothing in Droon is safe! His beasts have found a lightning-powered submarine hidden in the secret Fortress of the Treasure Queen. Now Eric and his friends have to stop Ko before he destroys Jaffa City. But first they'll need help from their worst enemy -- Lord Sparr. If he can be trusted.
