Now that Tetra is pregnant for real, King Abram better remember that having bloodlines everywhere works both ways in terms of gaining authority.
Rosice could ally with the surrounding Kirishians to overthrow Abram and eliminate those with higher succession rights (first slowly then by force, pretty much copy paste what Abram said last chapter) to then place Tetra’s child at the top. Rosice can then either sell the territory or keep it as a colony/vassal state.
Gehena is already not in friendly relationship with their neighbors. In fact since Abram was considered an usurper of the former colony, the neighbors probably enjoy the irony of him getting usurped.
So… scheme too much and it will come back to bite you.
