Salvo

Mostly likely yes, last I heard that it was supposedly a Vanderguan warclaim 

GMs haven't even responded in the warclaim chat (I'm in it). I don't see why it would be valid any longer considering the staff said it was the Orvars who were doing the attacking. Vanderguan is pretty much gone now, since Sutica and the Orvars have left.

The short answer is no, to the best of my knowledge
