Simple enough, just create your own timeline of the events during and after Skyrim, up until the rather inevitable second war with the thalmor, or heck, say that something else happened!
Remember, start from 4E 201!
Go for it!

4E 201- Alduin is defeated, the emergence of another Dragonborn occurs.
The Imperials win the Civil war in Skyrim using the help of the Dragonborn Legate
Miraak is defeated by the Dragonborn and Solstheim is saved
Harkon is defeated by the Dragonborn and the world is saved from being plunged into darkness
The last remnants of the Dark Brotherhood are destroyed by the Dragonborn
4E 205- Peace negotiation begins between the Empire and Hammerfell
4E 206- Green Sap, in Valenwood, is unknowingly starting to die (In truth the Thalmor have deprived it of it's stone, see towers lore)
4E 207- Hammerfell is reinstated into the Empire after two years of brokering a deal
4E 207- Thalmor aggression increases between the borders of Elsweyr and Cryodill. A group of adventurers are killed by Thalmor agents near Leyawiin
4E 209- Behind the Thalmors back, the Empire begins to regain it's strengh by brokering a deal with Hammerfell and High Rock. Valuable materiels are shipped into Cryodiil, as well tactics the Redguards used against the Thalmor.
4E 211- Thanks to the work of the Dragonborn in 4E 201, Solstheim begins to trade valuable Stalhrim and other goods with the Empire
4E 212- The Second War with the Dominion breaks out when Thalmor forces ambush and sack Leyawiin and Anvil
Skirmishing between the Gold coast begins.
Several Thalmor leaders are assassinated by the newfound Blades/Penitus Oculates
Emperor Titus Mede II dies from ill health. His son, who has trained his whole life for war, takes the throne
White-Gold concordat abolished
4E 213- For the first time, the Thalmor are pushed back. Reinforcements from Hammerfell break past the Elswyer-Valenwood border and begin to slowly but surely gain some ground
The Dragonborn Legate is promoted to General for his deeds on the field near Anvil
Worried for their culture and lives, some groups of Khajiit betray the Thalmor and turn over to the Empire
4E 214- Northern borders of the Dominion occupied
Fierce Naval Battles near Stros M kei ultimately go in the Redguards favour. This gives a port for attacking Alinor.
The Nord legions, led by General Rikke, regain Leyawiin and are now driving back the Thalmor from Three fronts.
4E 214-216 Yet more fierce fighting
4E 216- Alinor is captured by forces led the Dragonborn after nearly 4 months, Valenwood and Elswyer are liberated and have begun to reassemble some form of Government.
Happy endings for all
