Yup, good call. But azuarc got it
I met my end questing for the crown to a collection, though scattered.
Sir Amiel's skeletal remains, along with a journal detailing his failure, can be found in the same room as the Helm of the Crusader, the "crown" of the Crusader's Relics, which are scattered around Cyrodiil in various chapels and dungeons.
Those virtues I failed to uphold in life, I uphold in death.
Almost a direct quote from the ghost of Sir Amiel. Though he failed to defend the relics when he was alive, he and the other knights defend them as spirits.
I thought I had failed, but I was redeemed by Bendu.
At his time of death, the order had ceased to exist, and the Crusader's Relics were scattered. However, the player character (Bendu Olo, by default, according to the CS) revives the order and collects all the relics.
I lied in wait, and though I was victorious against many,
His spirit waited in the KotN chapel, guarding the relic, for a champion to challenge them for the right to take up their quest. They defeat every challenger for 300 years.
They, through their demise, failed me.
Although Sir Amiel and the other knights were victorious, the fallen challengers had each failed them in the sense that none were strong enough to quest for the Relics, until the PC.
