Blade Burrower

Blade Burrowers were powerful Rahi who lived in the Onu-Metru Archives sub-levels. They menaced Matoran for years, digging tunnels that resembled Matoran-made ones. Matoran often mistook their tunnels for parts of the Archives and wandered down them, never to be seen again. They had poor eyesight and thus hunted mostly by smell. When food was scarce, they would wander up into the more-visited parts of the Archives and cause Vahki lots of trouble as an enraged Blade Burrower would use its tail as a flail against its enemies. There were only a few, but Visorak had little success in capturing them. Rahaga Bomonga mapped their tunnels and found that the Blade Burrowers appeared to be building something. What they were building turned out to be the Matoran symbol of "Unity, Duty and Destiny".
