"See azure lost amidst the squall."
While back in XI azure stood for BLU, here it DRG. It could simply mean that DRG story is coming to an end as we say goodbye to Heavensward and start our descend into Far East patches/Bloodstorm.
Though one can hope and trust me, I'd love to see BLU come into this game but, I don't think it'll be in Bloodstorm.
