It is said that after defeating the Tsaesci, the vampiric serpent race from Akavir, Ka Po' Tun plan to invade Tamriel.
Ka Po' Tun has recently defeated the Tsaesci, and now, stronger then ever, turn towards Tamriel.
With Cyrodil having the simplist terrain, and lacking an Emperor, they decide to start the attack there.
Sailing into Topal Bay, the Ka Po' Tun plan to take Leyawin and Bravil before heading upriver to strike the heart of the Empire.
The Imperial City.
Since i don't want to muck with previous History, this will be set in 4E13.
Although still without an Emporor, Cyrodil is semi stable under Ocato, with the war causing in-fighting among the Elder Council.
With Half of the council power hungry and desiring indefinite ruling power over the Empire, and the other half desperately seeking an Emperor, The Imperial Legion cannot successfully defend Cyrodil due to the division among the members of the Elder Council.
Limited help has come from the other provinces. The Elder Council has insisted in its contact with the other provinces that it is a minor issue and none of the troops sent by the other provinces are allowed to send letters back to their respective homelands.
The Empire is in trouble, and it's up to you to save it.
You can fight to hold back the enemy, work to reunite the Elder Council, or attempt to get word through to the other Provinces of Tamriel.
You may be an Imperial Solider, a Leyawin City Gaurd, a Citizen of any of the cities of Cyrodil, a member of the Mages, or Fighters Guilds, it's up to you.
