Ishgard Residence

So although you would get access to the area in 3.0, you cannot buy there until you have finished 3.3.

I just finished HW proper on an alt and the NPC that opens up Empyreum still does not have the blue quest marker that unlocks it. I knew the "note on the wall" that unlocks the Firmament area doesn't appear until after 3.3 so I guess they added the same (silly) gate for access to housing.
