The Terenarc, also known as the Arcanix Terentatek, is an aberration of the terentatek specially suited to survive Arcanix’s harsh landscape. While normal terentateks have proven to be very adaptable, even in an environment as harsh as Arcanix, the leader of the Cult of Shadow, Sivter, saw that the creature could be improved even further. The project was given to Uvon Okdoro, the cult’s Master Alchemist in the field of biology, who developed a strain that incorporated the traits commonly seen on Arcanix by other creatures.
