TUA-46

Tri-Unumic acid, or TUA-46, is a highly toxic liquid mainly used a weapon of war. However, it got forbidden in the World Union Convention in 192 BD. It is generated as a byproduct of an old method of rapidly developing photographs.

It is easily diluted with water and is not very reactive.

Health effects
Most people who come in contact with this die within 2 days because this poison binds with the ADP molecules in your body, therefore making the body unable to create more ATP from ADP. The body soon dies because of insufficient energy.

Some people, often called semi-immune, have the ability to unbind TUA-46 from ADP. These people do not die. Instead, these people find that it reacts with serotonin receptors, causing a mental imbalance. The TUA-46 also replaces Hemoglobin, coloring the blood green-blueish to yellow-green, depending on the amount of oxygen in the blood. Suprisingly, TUA-46 seems to work good as a replacement for Hemoglobin: sometimes better, sometimes worse, depending on the person. This condition is called Unuminosis and will usually set in after 12 days of exposure and can take 1 year to fully clear up.

Used in medicine
TUA-46 is sometimes injected with pre-bound ADP. Due to this, it'll still replace hemoglobin but will not kill. This is to treat poisoning by Carbon Monoxide. When TUA-64-containing blood cells die, they do not release any TUA-64. Instead, it reacts into water and Unumium, a radioactive substance. This substance will leave the body through urine.

Immunity
The only cases of immunity were the scientists in Amsmark. This is still a mystery as no antipoison has ever been found and the chances of 132 people being semi-immune is slim.
