Siege of Orsinium

Prelude
The mighty Orsinium becomes a threat to the neighboring kingdoms. King Jolie of Daggerfall sends a letter to Gaidan Shinji of the Order of Diagna, proposing a joint attack on Orsinium. The alliance is formed, and this effectively reduces teh feud between Redguard and Breton, and now both races focus on a single common foe, the Orcs and beast folk of Orsinium.

Battle
The Bretony forces of Daggerfall, the Redguard army of Sentinel, and the Order of Diagna join forces to invade Orsinium. However, the Orcish Kingdom of Orsinium proves to be too powerful. The Siege of Orsinium takes a long 30 years, consuming great warriors and heroes. Among them is the famous swordmaster, Gaiden Shinji, of the Order of Diagna. To this day, the Orcs are still renowned for their battle prowess.

Aftermath
The forces of Sentinel significantly weakened by the Orcs, even more so than their allies. Daggerfall seeing this weakness invades Bankorai Pass, a strategic mountain pass that connects High Rock to Hammerfell (formeryl Volenfell).
