Not long after the Brotherhood's creation Korzak started plotting. He rallied up followers and together they plotted to bring down Mata Nui. However, Makuta Mutran kept a keen eye on them and reported back to Miserix with their doings.

Miserix sent a troop of Makuta and Rahkshi to invade their base. It didn't take long to penetrate it and a huge battle soon ensued. There where heavy casualties, and eventually Karzak and his surviving followers escaped the Mata Nui universe.

Shadow Confederacy

Korzak landed on another planet and quickly conquered it, discovering powerful technologies and men there. He has managed to return to the Mata Nui universe and made his headquarters on the hidden island of Aural, a island hidden away from Teridax himself. He then created a alliance known as the "Shadow Confederacy".
