Hey, Arcturus, I'm Sirius, your - well, something something down the line nephew or something like that. Cassiopeia's brother Pollux was my grandfather. I think. I don't know, the whole family tree is ridiculous.
As far as your father goes, he isn't here. In this realm, I mean. Not here in Night Vale and not in London either.
I'm not - he'd better not be a complete arse at this age
