User blog comment:CaptainAndrath/Constantine Valdor alive?/@comment-3258762-20130227220414

We've had the conversation and it seems that the general concensus is that marines are not immortal.

However, on a more important note: I do not believe Valdor is still alive. He was an incredibly important figure in the years after the HH and he would have been almost forced to re-join the High Lords again for his wisdom. Think about it, if Valdor was still alive, could Goge Vandire have taken command? The same Valdor who was active, unlike most modern custodes, the same one who saw what happens when you defy the will of the Emperor?
