So that female emissary turned out to be someone very important. That was a lot of roles she used to fill from 500 years ago alone: ex-slave, wife, and then assassin of the "great king". Now she's a witch who's the creator of voodoo magic, the Prime Minister of her kingdom and its emissary; not to mention she's over 500 years old and is an acquaintance of the legendary Griffon. Phew, that's one long description for her and it doesn't even include what she looks like.
The newlyweds got down to "business" quickly. Now I wonder who's gonna bear the first child: Tetra or Yulia? They're not gonna race are they...? It would be great if their polygamous marriage would become polyamorous (because then they don't have to solely depend on Almus for love), but that realistically would only work if both Tetra and Yulia were bi to begin with.
"The late king is unconscious"
Err... I don't think you can call someone "the late" unless they're dead. That makes it seem like Almus intended for him to die. "Former king" would've done nicely.
