But unbeknownst to Mata Nui he is actually being stalked by a Zesk, Mata Nui then stumbles to Volcanus when we is questioned at the gate, but it eventually let in by Raanu, believing that the battle that would soon occur in the arena would help calm down Mata Nui from his panic.
In 2010 the six matoran have met up with a young rogue skakdi, 4 more matoran, and 1 new toa. together they would travel farther down to the south and would get into a scuffle with 6 Skakdi Warriors, but the goup would outright slaughter the 6 skakdi and continue on.
