Well the lore card places Rezyl directly where the dead titan lays. And the card said his light would shatter. When we come upon the dead titan we discovered that he had no ligt left not even a spark to reanimate. Then we find his dead ghost which we learned earlier that it was probably the one that was messing around at the lunar base station. People say the time line doesn't fit because they said it talked about recent activity. The recent activity I believe came from his ghost as he was trying to warn the vangaurd.
