Deletion of High Lords of Terra

Comment: Not much to this.  Plot material.  All in universe.  Almost zero impact on 40K the game (As well as 40K the fictional setting).  No reliable secondary sources discussing the topic.  Fails  (this is debatable depending on your interpretation) and  (this isn't, really).  Again, for the sake of discussion, the sources provided are produced by Games Workshop in order to sell workbooks, fiction and toys.  They don't write codexes because there is a rich game world to chronicle.  They create the rich game world in order to sell codexes.  This distinction is important in considering why  should apply here
