Awakening (144 cards, released May 2001): This set introduced a new region, the Core, and provided preview cards (one "Hyren" creature each) for the regions of Weave and Kybar's Teeth. This set also featured a Shadow Magi for d'Resh, a region not released until Voice of the Storms.
Awakenings was the first expansion and the second set to be released, both in the US by Interactive Imagination with an English language version and in Japan by Epoch with a Japanese language version. The expansion features Core, a new region, and introduced special rules for the denizens of the centre of the Moonlands.
