Zemya

Zemya was an Onu-Matoran.

Mata Nui
Zemya was awakened by the Turaga and lived in Onu-Koro. Zemya may have been a guildmaster, and was angry when Onu-Koro seemed to be sealed off tradewise from the rest of the island. He was evacuated along with the rest of the Onu-Matoran when the Gahlok attacked.

Return to Metru Nui
Zemya presumably moved his shop to Metru Nui when the time came for all Matoran to go back to their home. He was repairing the city until the Staff or Artahka repaired the universe.
