25 - Division of the Black Feather

This man (being ... whatever), Asmedaiel, was featured in Dante's video ASMEDAIEL UNHINGED_ CASUS BELLI.

Casus Belli is latin term for the justification for a war. In other words, the 'public' version of why war is being declared. It may also refer to the private reason, but that would only be discussed among the highest of the high.
