The more recent one is from Ogmot's journal, which was dropped by Ogmot in Silithus at the pre-patch of BfA and he wrote 'the first one been told', which is why most people (me included) looked for a possible lie in Anduin's speech that he gave in the epilogue of the Argus-campaign (so right before he sends you to Silithus and you can find that journal.)
