Trilanic activator

A trilanic activator is a device created and used by the Zygons to control their Skarasens. When activated, it sends out a signal that says "eat me, eat me" and calls the Skarasen to wherever the control is. Like most Zygon technology, the trilanic activator is biological in design. It is hand-sized and has a texture like wet skin. It will activate and can be regenerated when in an area of high diastellic transmissions.

The group of Zygons used a trilanic activator in 1909 to control their two Skarasens. (TDA: Sting of the Zygons)
