Because Khorobirit isn’t by the sea.
Khorobirit learns and he got some other Princes to think about this stuff too. Jughsavil and Norribirit for one. He’ll also force the Antari to change as well to prevent Khorobirit from dominating them.
Secondly, do you think that’s enough to save them from Takara and Kian? I have a feeling that Khorobirit roaring at the top of his lungs that he wants Miguel dead and Tierra a chattel house will inspire… drastic measures especially if he becomes Tsar and Autocrat of all the Antars.
But that’s just me and besides, this is always a fun little debate.
