Chute

Protodermis Chute
A chute was a pipe of liquid protodermis held together by a magnetic field. They were used to transport Matoran, cargo, and Rahi. They were also used by Chute Lurkers to hunt.

Occasionally the fields would fold in on themselves and form a deadly sphere that would travel through the system until it eventually imploded, killing everything caught in it. This was known as a force sphere.

The Le-Matoran who ran the system feared that reversing the flow could cause the entire city wide system to destabilise. Nidhiki once forced Kongu to do just that but it had little, if any, negative effects on the system.
