Spiriah

Spiriah was a rogue member of the Brotherhood of Makuta, and was assigned to the island of Zakaz. He was known for giving the Skakdi their elemental and eye vision powers. The Skakdi went mad with power and banished him from the island. Since this failure, the Brotherhood of Makuta were loooking for him him.

He forcifully joined a team of rogue villains, including Brutaka, Roodaka, Vezon, Carapar and Takadox. While the group was on Stelt to acquire a boat, Spiriah had figured out that Brutaka was after Miserix, and sent a message to a tribe of Zyglak to attack the group and assist him in taking over the ship. but the Zyglak were defeated by an aquatic army consisting of Ehlek's species. Spiriah was quickly defeated by Brutaka, and was allowed to continue the mission, albeit under closer supervision.

When the team arrived on Artidax, where Miserix was held, Spiriah was nearly killed by living sand rigged to recognize the presence of a Makuta. He was rescued, and Brutaka convinced him to act as a decoy to further traps and guards.
