Caius blames himself for Berich becoming what he turned into, saying that if he hadn't drawn his weapon and fought his friend none of it would have happened. Despite this, he had hoped to reconcile with his friend in the after life, something that has yet to happen as his spirit never arrived to guard the last relic.
Sir Caius is first encountered by the Hero while they are searching the Priory of the Nine for the Cuirass of the Crusader. Sir Caius, as well the rest of the knights' spirits (excluding Berich) are in the under-croft guarding there only remaining relic they have. Sir Caius and the rest of the knights will each fight the Hero to see if they are worthy to take the Cuirass and be told where to find the rest of the relics.
Gauntlets of the Crusader"The Gauntlets were recovered by Sir Casimir. One of our few victories during our time. But then even our victories became our failure."
Knights of the Nine"In death, we continue the work that escaped us in life. The relics must still be guarded, for some day they shall be needed once more."
Mace of Zenithar"Sir Ralvas requested for the Mace after Sir Berich's betrayal. He believed that with the Mace, he would be able to bring the rest of us together. He stayed at the Chapel of Leyawiin for months, attempting the test over and over. He hardly ate. Hardly slept. In the end, he failed. He left the chapel broken and beaten. Sir Amiel found his body and laid him to rest here at the Priory."
Sir Berich"Alas that my old comrade is not among us here. We do not know why his spirit did not join us here to guard our last Relic. We were enstranged in life, but I had hoped that in death we could be reconciled. For my part, I now know that I am largely to blame for the ruin of the old Order. Sir Amiel takes too much upon himself. I will say no more."
Sir Berich (After obtaining all artifacts excluding the Sword)"Alas that the evil has begun on the day of my death should have struck so deep! When Sir Berich said he would take his Relics with him to war, and would not listen to Sir Amiel's pleas, I allowed my anger to get the best of me. Know that I was the one who drew weapon first against Sir Berich. He merely defended himself, and proved the better swordsman. And now, because of me... evil has claimed his very soul."
Sir Berich (After obtaining the Sword)"You put right the evil that I began through my own weakness. Sir Berich is once again part of our fellowship, and shall be forevermore."
