Malekite's quest to steal the domain of plagues and diseases is why the kingdom of spores is enemies with the kingdom of Sharat. The kingdom of Sharat is owned by the god of ghouls. This is a low god with a domain of plagues and diseases.
The two kingdoms are at each other's throats. The god of ghouls wants Malekite's domain of spores. With it, he will be able to spread his diseases better. So he welcomed the challenge from her.
That challenge had escalated today. It is because Malekite was attacked a few days ago. It was a mysterious attack that bypassed the defense of her divine body and struck directly at her godhood. That attack rattled her and made her lash out in retaliation.
The first person that came to her mind as the culprit was the god of ghouls. She didn't know what he did or how he did it but she wasn't going to allow it to continue. Being passive is a bad idea. It made her rouse the entirety of her army to attack him immediately.
