Forum:Canonicity of "Realms Apocrypha"

Hi everyone, I've been puzzling over one citation for http://forgottenrealms.wikia.com/wiki/Artemis_Entreri, namely, the alias of "Belmer", which exists in the Double Diamond Triangle Saga. However, the DDTS, despite being published by WotC, had been declared as non-canon by WotC. As such, should this alias even be on that page?
