The quest for the World Stones concludes here! Charles must beat the Wraith Queen to at least one of the three Stones, or she’ll open a portal and summon an unending horde, enough wraiths to suck all life from the world. At all costs—no matter how great the loss might be—at least one of the Stones must be obtained, or all is lost! But getting a Stone is just the beginning. World Stones are virtually indestructible, so even if they win one, how do they keep it from the Queen forever? To save the world, Charles will have to combine logic with magic if he’s to end the threat of the Wraith Queen for all time!
