Zantraetium

Zantraetium is a mineral indigenous to Andor. Some batteries are composed of zantraetium. However it is not used in Federation starships.

In 2382, an andorian extremist namend Threlas ch'Lhren placed an experimental transceiver aboard the Enterprise-E in order to infiltrate the ship's computer and later take the ship hostage, as ordered by his superior, Treishya leader Eklanir th'Gahryn. They tried to force the Enterprise to leave the system and abandon Captain Jean-Luc Picard and other crew members. However T'Ryssa Chen found the device in Engineering.
