Also, honestly, it feels to me in hindsight that Heavensward was an expansion where they wanted to fit as many double entendres onto the expansion title as possible.

Heavensward... We go up into the sky islands that float and flying is introduced to the game. Yeehaw!

Heavensward.... There's literally a Heaven's Ward that are part of the major antagonist.

Heavensward..... even into the .1~.5 patches major characters die or are hurt in the extreme. There's a lot of loss compared to other expansions, as if to say, "They went to Heaven." Heavensward.
