this is just a thought, you get a message to travel to throat of the world, esbern or paarthanax depending on sidequest choice tells you the "time rip" is acting funny.a bright flash ensues blacking the screen , you wake up surrounded by elves that say themselves to be dwemer or "dwarves".they explain where they were,how they "disappeared" and why they returned (you opened the elder scroll hurdling them back) you get a message from an npc, telling you the falmer mounted from the depths of blackreach an attack on the surface of Skyrim. The dwemer described what they did to the falmer and why they would want to attack and the dwemer goes on to say " if the falmer are not stopped dawn will cease to exist and Skyrim will forever be blanketed in darkness. You fight the falmer in small quest skirmishes which leads you to find out that the only way to stop the falmer and save skyrim is to kill the "snow elf prince" you also find out that the only way to break through the princes dark magic is to find, depending on your skills enchanted arrows, sword, or spell in an new location filled with other quest upon finding it you return skyrim and in a massive quest ending battle you kill the prince. After the quest the new location is fully accesible, the dwemer continue trying to rebuild their culture giving you new quest and weapons (including crossbows) the new vampire animations are just gameplay mechanic enhancements.
