Obsessive Adrenal Tendency (OAT)
OAT is manifested in the desire to go through an adrenaline rush. It is often the driving force of the thrill-seekers and daredevils of Yudryae. Due to the low content level of oxygen in yudryaen, copper-based blood, an adrenaline rush gives the individual more energy, causing them to become addicted.
The Aisri were the first to discover a type of treatment; tea made from the leaves of an Irreafron plant. The ritual of drinking this tea became a daily occurrence for them, and slowly, they sold this tea to other races as well.
Not many are all that aware that this is even an illness. It is an invisible illness, seen as a normal part of the Yudryaen people. Only the aisri are faintly aware of it's danger.
