So, my Khaine End Times books finally arrived, and I am on the pages where Araloth and Lileath are traversing Nurgle's realm. It's a fun read and describes in detail what his realm looks like (Nurgle is at the Court of Covenant during this time with the other gods) as the pair try to rescue Isha and Vallaya. They run into a human sorceror tasked by the gods to chart and map the realms. I think this is the same guy who wrote the Liber Volumes. I think he was mentiond in Tome of Corruption, too.
But there's a Silver Armored Knight in here too who I can't figure out who he is. The book doesn't name him, but it doesn't name a lot of Characters. We only know of them by deed and cross-referencing (for instance, Skarbrand is mentioned in this book, but he is only ever referred to as a 'Colossal Bloodthirster'). The Knight was spreadeagle-bound by vines and later mentioned he had made a name for himself among the Daemons of Nurgle's realm. He dies aiding Araloth and Lileath's quest.
Does anyone know who this Silver Armored Knight trapped in Nurgle's Realm might be?
