Damn double post, and as you ask, if I miss anything someone I'm sure will add it in.

Some time before Sundas, Second Seed, 4E 205, the Empire starts a short war with the Dominion for Valenwood, Meanwhile the Akaviri expeditionary forces set sail for Tamriel. 

The Empire calls for a summit near the end of Second Seed, on Isle of Balfiera, in the Iliac Bay, between Skyrim, Hammerfell, and the many kingdoms of High Rock, mostly High Rock nations end up attending but it results in them finally choosing a high King, more or less. 

In the 18th of Second Seed in Torval the captial of Elsweyr. The Mane is assassinated by a Ka Po' Tun mercenary paving the way for a longish and bloody civil war that pretty much leaves Elsweyer in the dog house seemingly for the entirety of the RP. One faction of the Civil war, in the north, are pro-empire, the south forces are pro independent, seemingly cause common sense is not popular in the south.

In 2nd of Midyear, 4E 205, Argonia invites the Empire and any lords who wish to attend a summit in Stormhold on the 26th of Midyear. Most of the major players of Tamriel make attendance, despite this, it largely succeeds in doing very little. At least anything that would prevent the ire of the dark elves. (the invitations officially are handed out in 15th of Midyear, 4E 205)

5th of Midyear, 4E 205 a Skirmish in Stros M'kai reveals the location of Pirate Lord Dupont. Like many things, it means nothing.

In 12th of Midyear, the Akaviri finally reach Ynslea, The Dark elf leader Oravos, pretty much goes to bed with the Eastern leaders, in that he begins making plans with them in order to support the Akaviri in their conquest, in the hopes his lands and people might be spared. 

Loredas, 28th of Midyear, 4E 205, Pirates and brigades start taking advantage of the Civil war in Elsweyr, the nation is further ravaged. The Empire becomes whimps again and sign a peace treaty with the Thalmor. 

22nd of Midyear Alinor finds an Elder Scroll (and continues to repair the Crystal Tower.)

24th of Midyear in Senchal The High Elves kidnap (catnap?) a child from Elsweyr believed to be the mane. Everyone goes on to love the High Elves. Oh, and they also found Order of Whispers, a spy network. 

13th of Midyear, the Maormer, or Tropical elves, appear on the scene, scouting primarily in Elswyer and Southern coast of Valenwood. 

On 24th of Midyear, 4E 205, The Bosmer cedes over massive territory to the Redgaurds, practically becoming a client kingdom. In return they are offered Protection. 

25th of Midyear, with the use of yet unseen flying messengers, Alinor panics the hell out and sets sail for Valenwood. The Sea elves meanwhile begins research of explosive snakes and a butt load of other weapons, magick`s and tactics. 

 3rd of Sun’s Height, The orcs secretly begins training large groups of rebels who seek to overthrow the High King of Skyrim, Jatrod the Righteous. They also send out a warband/adventure group to seek out Volendrung in Skyrim. Something seemingly forgotten about later on. 

Skyrim starts a short campaign on the 24th of Midyear against the Reachmen, it's success can only be measured in the amount of lives lost and blood spilt at the cost of Skyrim and the Nords. The Empire makes contact with the Maormer, the latter also makes contact with the Dark Elves later on. 

25th of Midyear, 4E205, 200 proud and brave Argonian set sail to Southern Elswyer in order to lend aid to the southern forces. However, by the time they land, the war is over in favor of the north, though it had cost the Khajiits immensely. 

20th Midyear 4E, 205, Morrowind soon begins arming much of House Redoran with Akaviri styled weapons. Cause Katanas are cool yo. While also Increasing amounts of Hearthstone Golems.

On 26th of Midyear The battle of Stros M’Kai Bay begins largely between The Yokudan Fleet and the Royal Alinor fleets and ends in a Pyrrhic victory for the latter, leaving both fairly devastated. Ironically, this solves all pirates problems in the Abecean Seas. Biggest naval battle to grace Tamriel ever and it ended way to fast. 

6th of Sun’s Height, Gives rise to the 'Rebel Queen' who will soon lead the Skyrim rebels to glorious victory against the much hated High King. (never did learn exactly why they hated him, but they did.)

Tirdas, 1st of Sun's Height, 4E 205, The famous wizard, Tolfdir, passed away at the age of 127. His last words, according to the College staff, was, "Where is my alembic?". The Empire's attempt to gain battle trolls from the Dawnguard ends before it begins with the murder of their representatives there by vampires. No further attempts were ever made to gain war trolls. More importantly, A disease called the Cyrodiilic Disconnect have been spreading. The infected reported out of body experiences and feeling of their soul being drained away. So far, no fatalities. (Many figure it's just some rather intense Skooma highs)

28th of Midyear, 4E 205 An-Xileel peacekeepers, are rather pissed off at the Empire for supporting the Northern forces in the Civil war in Elswyer, never mind they technicality never played any part in it. They almost go to war over it...thankfully cooler heads prevail. 

2nd of Sun’s Height, 4E 205, the Orc's are robbed in the night by unknown thieves, most of their armory being robbed, many suspect magic, the Orc's blame the Redguards cause their black I assume. Either way they begin marshaling their various tribes for war. Don't let no body rob you in the hood and you not doing something about it yo. 

And oh yes, the Akaviri finally land in Windhelm, Thorn and Winterhold, the first two are sacked, the latter is brought to total and utter ruination. (as if there was anything to destroy there in the first place.) The Jarl of Windhelm believed it a good idea tactic to challenge the invaders to single combat.. thankfully he was later fired....and iced...and lightninged. 

26th Mid Year, Pyandonea, starts buildings a navy for Morrowind, the nine alone now how their getting the chitin, but leads to reactivating two more shipyards. They also join the Akaviri in invading Black Marsh, cause why should only the Dunmer and Akaviri get to commit mass suicide in Black marsh alone? Meanwhile in Alinor, a small civil conflict arises between the Government and the Thalmor (who btw no longer control Summerset), it results in the Thalmor's most recent bid for power failing. 

27th of Mid Year, Most of Greater High Rock besieges Wayrest, Bretons still uninteresting. 

8th of Sun’s Height, 4E 205, Orsinium hs gathered most of it's tribal allies for the biggest moss pit in history. Meanwhile those Orc Adventurers arrive in the Rift, and the rebels have finished their training and have marched on Falkreath Hold. 

2nd of Sun’s Height within the bowles of the Crystal Tower, the baby mane is murdered in cold blood, this in order to gain control of the Moons and creates the The Wand of Secunda, this also results in a week long blood moon, which probably wrecked havoc on the seas. (Secunda is the one that became a Bloodmoon, beware of werebeast.)

On 25th of Midyear, Hammerfell and Empire make a secret pact to crush the Dominion while they are occupied elsewhere. 

9th of Sun's Height, some of Morrowinds golems explode, their Armigers march to support the Akaviri invasion in Skyrim. Meanwhile the Khajjit continue to rebuild and recruit. Alinor and Pyandonea start trading. 

12th of Sun's Height, Empire hears word of the Akaviri invasion in Skyrim, and panics the hell out, marshaling of Legion's begin, messengers sent to the North western nations. 

Aaaand, that's pretty much it, someone can add or correct where needed I'm sure. Should be warned this is written in classic TES style, so bias remarks ftw!
