Erbil L5 is a virus created in B3W by an unknown country and was first discovered in Erbil, a city in Iraq. Erbil L5 was designed to target specific crops and destroy them, causing famines in the Middle East; it is believed to be one of the causes for World War III.[1]

At the start of A3W, the ABN admitted the country who created Erbil L5 into their faction and destroyed every trace of the virus. Future storage and development of viruses and bioweapons would become prohibited worldwide.


Phase 1: For You, the Replaceable Ones

In Chapter 17, Erbil L5 suddenly re-emerges because of the Three Kings and destroys 30% of the world's crops before being suppressed. The ABN, which was unharmed by the outbreak, is implicated in the virus's spread. Rethabile suggests that the ABN was experimenting on their crops to protect them from Erbil outbreaks.

In Chapter 21, Erbil L5 mutates and breaks out again, attacking ABN crops.
