Metru Nui - Ahkmou
In the time before time, Metru Nui, City of Legends, faces danger unlike any it has known before. A mysterious and powerful menace threatens the city, striking from the shadows and then disappearing, leaving rubble in its wake. Six Matoran hold the keys to its defeat, but they have disappeared! Worse, one of them has been touched by darkness and plots against all of Metru Nu.
Ahkmou loves to compete, but always seems to come in second best. Now he plots to change all that -- and Metru Nui may never be the same!
