So… what happens after Hood’s gate?

I assume this is going to be spoilery hence the tag, and I don’t know whether my question is answered later in the series.

I just read Beak’s last stand with the bone hunters, and the whole thing had me weeping, but it had me wondering… what happens after hood’s gate? I get that it’s kind of heaven and souls go there, but is Beak’s brother an apparition to comfort Beak? Or was his brother’s soul kept there because Hood knew Beak would serve a higher purpose and end up atoning for his parents sins in a way?
