Two days ago, Chapter Four of Dark Mirror became available for download from www.bioniclestory.com.

Toa Tuyet leads Takanuva, Takua, and Dume far into forgotten parts of the archives. When they arrive at a chamber where two darkly-armored beings wait, it is the Makuta of Metru Nui who shapeshifts from Tuyet's appearance to his own, that of a large titan wearing an infected Hau. The Makuta are fugitives, they explain to Takanuva. Makuta's Kraahkan is warded; Tuyet leaves it on exhibit as a taunt to the Makuta, as she will know the exact moment anyone should lay hands on it. Takanuva tries to tell the Makuta that he is not on of Tuyet's Toa: he is a Toa of light from another world. The three Makuta, especially the one named Krika, laugh at the idea of some hapless Toa crossing into another dimension. They do, however, offer to aid Takanuva in finding the legendary guardian Brutaka if only he perform a favor for them: to intercept a Matoran ship sailing from Artakha to Metru Nui and seize the Kanohi Vahi from the crew for them. To Takanuva's shock, the Toa-radical captain of the vessel is none other than Matoran Jala.

Predictions: Obviously, Takanuva is going to have a dilemma concerning Jala. It is possible that in Tuyet's universe Jala and Takua had a falling out of friendship -- one agreed with Toa rule, the other did not. I think it is clear that Takanuva is going to accept the mission.
