The Tendo Biocoral Controller is presumed to be a control system for genetically engineered coral. Coral is controlled through bio-electroconductive slime. Can be caused to grow in multitude of shapes and functions.
Device appears to have been hacked together using a modern computer game console and augmented with bio-circuitry.
Additional evidence found in Green Bite suggest bioengineered coral was used in the construction of housing, cathedrals, food production.
