The Gathering

A dragon, two wizards, and an assassin travel to the world of Drago, named after the many types of dragons living there. The first objective was to save Magda's aunt and grandmother, but when they find that Drago and Earth have a rift that needs to be repaired or both worlds will destruct, they have to change their goal.
Earth, the planet 'with no magic,' is the next stop on their odyssey.
