Kerborus? Typo? Undefined term?

[Jarylan]

Was reminded of this today. When Kiona says this, is it a typo and my Steele's name should be there? Is it a korgonne term I merely missed the explanation of?

What in the world is "Kerborus?"

 

[Theron]

In context, it seems to be a title.

Kerberos is an alternate spelling of Cerberus*. It might be derived from that.
*The three-headed dog that guards Hades in Greek Mythology.
