Feral

A feral was a Drakonus who had a specific biological disease. Succumbing to the disease was commonly called “going feral”.

The disease affected the brain, deteriorating the more logical brain functions. Slowly, the affected Drakonus lost the cognitive thought patterns and became nothing more than a predatory beast. The exact cause of going feral was unknown, but it did not appear to be genetic.

Ferals were required to be reported so they could be put down before they became threats. There was no widespread treatment or cure; Rin Sakaros and Vos'elk'eetash managed to save Jadian Star from going feral through the use of, but in receiving their treatment, Jade became permanently stuck in Human form, unable to shapeshift, as well as experiencing some premature aging.
