Perhaps (I hypothesised freely) the Prophet believed that the fifteen people who inhabited my Halls should be counted as one set of People, while in the Far Distant Halls there lived another set and he ought to be counted as one of them. Perhaps among his own People he was the Third Person or the Tenth. Perhaps he was even some dizzyingly high number like the Seventy-Fifth Person!

But I digress into what is surely fantasy.
