Antro-Nui

Antro-Nui used to be known as "The Island of Slaves" as most weapons, armor, and other items were made by theives and murderers imprisoned and put to work on the island. When Makuta Pardex was banished to Antro-Nui, he somehow freed himself and all the other prisoners, and formed the Antro Alliance, a group rivaling both the Brotherhood of Makuta(Toa-Tera) and the Toa-Tera themselves.
