Heavensward seems to have themes of duality, understanding the past, reconciliation, and removing extremes.

Duality: Ishgard and Dravania, Hraesvelgr and Shiva, Estinien and Nidhogg, Hydaelyn and Zodiark, the Light and Dark sects of the Fists of Rhalgr, Lowborn and Highborn

Understand the Past: The awful truth about the Dragonsong War, Scions learning the Ascians motivations, meeting Tiamat, the source of the Tonberry plague in SCH quests, the entire Shadow of Mhach raids, Travanchet giving the horn to Mide

Reconciliation: Peace talks with dragons, Hraesvelgr regaining trust in mortals, Ishgard rejoining the Eorzean Alliance, Widargelt's goal in the Monk job quests, Rostnsthal trying to atone for his past actions, Urianger's gambit in 3.4, Lolorito's confession to Raubahn

EXTREMES: Nidhogg's vengeance, God-King Thordan and the Knights of the Round, Emperor Varis's policies, Quickthinx Allthoughts, the Warring Triad, the fate of the Thirteenth World, the Flood of Light afflicting the First World, Ilberd

While these themes also existed in 1.0 and 2.0 to an extent, they are most prominently displayed here.
