Because Emperor Keilusa is sickly and so was Kishiar due to their broken vessel, the emperor and empress adopted Katchian a move recommended by the House Diarca faction in an attempt to ensure a puppet king is seated. Hoep that helps.

Ohhh that helped thanks but one more question the imperial family's blood is sacred and special right? they're have the blessing of sun god but doesn't that mean the cp doesn't have that prestige because he's not related to them. Even if he were to succeed the emperor like he did in the previous timeline and have heirs won't the blessing of the sun god be lost because he's not of imperial blood? the empire would also lose a powerful of symbol of their prosperity how the hell were people convinced to allow for that potential future?

I wouldn't say its a blessing since Keilusa and Kishiar have weak vessels, Katchian doesn't have this issue. Katchian if I rrcall would be Diarca blood, a son from the Duke's cousin's daughter, a far bloodline so he doesn't seem to have an issue with his vessel. He looks blond and red eyes to make it seem he has sun god's blessing, but his real features are hidden by House Diarca. No one opposed Diarca because it seems other head dukes is interested in a puppet king. Keilusa and Kishiar have issue with their vessel so they had to agree to make him crown prince.
