Sir Amiel Lannus, also known as just Sir Amiel, is an Imperial knight ghost. When he was alive, he was the head of the Knights of the Nine, before the order fell apart. His ring unlocks the Priory of the Nine's secret underbelly.
Sir Amiel founded The Knights of the Nine in 3E 111, following his heroic return from the War of the Isle, with the purpose of recovering the Crusader's Relics, the weapons and armor of Pelinal Whitestrake, which had been lost for thousands of years. 
In 3E 121 when the War of the Red Diamond began, Sir Amiel was unable to keep his knights out of the war, due to the fame which the Knights were built on. The Knights of the Nine were officially dissolved, by Imperial decree, in 3E 131.
In 3E 153 Sir Amiel dies, attempting to recover the Helm of the Crusader in The Shrine of the Crusader, an Ayleid Ruin called Vanua, intended as the shrine of Pelinal Whitestrake. He leaves his journal which tells how to find the pieces of the Relics of the Crusader.
In his journal, Sir Amiel frequently blames himself for the collapse of the order and calling himself 'a foolish old man' regarding the departure of Sir Berich Vlindrel and murder of Sir Caius. At some time in the 3E 430's Sir Amiel guided the Hero of Kvatch (with the help of the ghosts of his fellow knights) to reunify the Relics of Pelinal Whitestrake, original Divine Crusader and predecessor of the Hero. Under the help of Sir Amiel and the other knights, the Hero found all relics and rebuilt the Knights of the Nine.

|Inside the Priory of the Nine:
"By the By the strength and guidance of the Nine, who comes before us upon this sacred ground seeking the Cuirass of the Divine Crusader? Step forward, adventurer, and face us each in honorable combat. For the vows we failed to revere in life, we shall uphold in death. No unworthy soul shall lay hands upon this sacred artifact without the leave of the Knights of the Nine."
After beating Sir Gregory:
"Sir Gregory, you are defeated. Sir Casimir, step forward."
After beating Sir Casimir:
"Impressive. You have bested Sir Casimir. Now, face Sir Ralvas."
After beating Sir Ralvas:
"Sir Ralvas, you have fallen. Step back and let the challenge continue. Sir Henrik, come forward and prove yourself."
After beating Sir Henrik:
"You have overcome half of us and yet you remain standing. Perhaps Sir Caius shall test your true mettle."
After beating Sir Caius:
"You show a fury of faith that I have not seen in centuries. But now you face Sir Juncan."
After beating Sir Juncan:
"You have lost, Sir Juncan. Sir Torolf, show the challenger the ferocity of the North."
After beating Sir Torolf:
"You have stood against the Knights of the Nine and lived. However, the final test is upon you. Ready yourself, Sir Knight, and face me."
After beating Sir Amiel:
"Sir Knight, in three hundred years none have stood against us and lived. Step forward and claim what is yours by right. May your faith be true."
If approached again:
"By the Nine, I've not seen such strength. Could you be... no. You cannot. You are simply a noble knight."
"May your sword strike true."
