The Next Emperor - Expediaing the Next Emperor?

In 225, Mamea arranges a wife from the Senator and aristocracy for several Alexander. This obviously used to avoid the problems that happened under Eligablas. Herodian doesn't even give her a name but we know from coins and inscriptions that her full name is Biana. Nia, Saya, Herenia, Celestia, Barbia, all Biana. So she gets the same title as Severus' mother. And indeed, there was no offspring from the marriage of Alexander and all Biana either. That would have gone down well. Yes.
