Kill The Warrogs.

So the Sovereigns refused to comply with the request of the fountain of life. They shouted and disagreed en mass. The plaza became rowdy and noisy despite the usual calm disposition of wood elves. 

The representative of the fountain of life remained silent and bore the criticism. It turned out to be a good idea. The sovereigns stopped shouting when they got no response from her. 

So someone asked her, "Why does the Fountain of Life want us to protect the Warrogs? Surely there must be a valid reason for this absurd request."

She answered, "The spawns of the demon God are coming to the surface and they will target the Warrogs. They cannot turn the Warrogs but they can feed on them to strengthen themselves. Protecting the Warrogs is in our interest."
