With the Sirens present, the plan was set. Originally, we intended to just cleanse Hannibal of his malice. But the ones who lived here, like Olamide and Zanele, exposed a conspiracy by Onye and some of Hannibal's women.
'Just how big do your balls have to be to even think of cucking a Revenant?'
Basically, Hannibal tried to unify the continent by taking a wife from all 54 countries. He ended up siring 77 sons and who knows how many daughters. This was normal, standard politics you see in fantasy anime and manga.
But the problem began with what happens afterward. While it sounded good on paper, establishing alliances with bloodlines also turned vicious. The question was who succeeds the king once he passed away?
This issue was typical for humans, but I believed Revenants would be exempt from such challenges. Only Amari exposed that the way Africa cleansed its malice was to have the "King" take it all and die.
