Frequently asked questions
- What were the Fields of Air in Bionicle?
- The Fields of Air were a stand of tall underwater airweed plants on the seabed beside Mahri Nui, near the lower end of the Cord in the southern ocean. Each airweed plant held breathable air sealed inside its tissue, released into the water only when the plant was disturbed.
- How did the Fields of Air keep Mahri Nui alive?
- When the Great Cataclysm sent Mahri Nui to the seabed, the impact released a cloud of bubbles from the disturbed airweed, which the Matoran gathered into a single dome of breathable air around the rebuilt settlement. Continuous harvest of the fields was required to maintain the dome against constant leakage.
- How was the airweed harvested in the Fields of Air?
- The Matoran could not work the fields directly because the surrounding water was mutagenic, so they tamed local Rahi called Hydruka, which could sense airweed from ordinary seaweed. Matoran handlers called Hydruka Guards, including Reysa and Kyrehx, supervised the work and gathered the released air.
- What happened to the Fields of Air?
- The Fields ended together with Mahri Nui when the Toa Mahri cut the Cord and Voya Nui sank back onto the town's location, crushing it between the rising mainland and the descending island. The dome collapsed and the airweed beds did not survive the impact in any organised form.
- Why could the airweed harvest not be recreated elsewhere?
- The airweed species was site-specific. Without the seabed conditions that had grown it, the harvest could not be reproduced elsewhere, so the surviving Matoran carried the knowledge and techniques but not the fields themselves.
