Jordan left notes about everything and somethings he made clear he wanted to be left unexplained and left to the readers imagination (like Nakomi), other things we might get in the encyclopedia that will be out in a year, we are also promised another book about Demondred so hopefully we get some answers out of those... But looking back now after more than a month since i finished the series, and have read an awful series since then(the deathgate series) got to say it was'nt such a bad ending as much i thought back then
