Talk:Siege of Castellax

Canon Source?

Since most or all of the Space Marine Battles (Novel Series) are based on battles referred to in the codices and rulebooks, does the Siege of Castellax have a canon source?--Proteus77 18:07, 19 December 2012 (CET)

I've never seen any no.--Harriticus 18:21, 19 December 2012 (CET)
