Lost Falmer
Choices in previous quests, seemingly irrelevant ones as well, to have a greater impact on this DLC, previous DlC's included. So if the above major battles against the Thalmor were added, you may gain support or face opposition from NPC's you met in the past. So your actions in 'Dragonborn' may gain the support of House Redoran/Telvanni forces in the battle. If you sided with the Volkihar you may have a Vampire Lord helping in the battle, if you spared Sinding you may him fight in beast form. It'd add greater depth to the actions of the Dragonborn, making you feel more involved. Oh and more Argonian NPC's
DLCs. Can't. Interact.
