User blog:Blueyhale/Should some Battle Reports from White Dwarfs be considered cannon?

Hi guys, just notice someting 'missing' on Warsmith Honsou's profile, about after the Siege of Hydra Cordatus and before his return to the Iron Warrior's daemon homeworld world Medrengard. Has any read White Dward 275: Gateway from hell battle report? and it was only mentioned twice in the Iron Warriors series. A secret gateway on the planet Perdictor that the Iron Warriors use but then they had a battle with a black legion warband led by Nechissar a chaos lord (captain) Van Daal but the Iron Warriors won anyway, so should the Gateway from Hell be cannon or not?
