Leofric first rose to prominence when still only a Knight Errant, unhorsing the fearsome Duke Chilfroy at the Tourney of Couronne, a feat none of the gathered knights and dukes ever expected to see in their lifetimes. The young knight went on to defeat every other opponent at the tourney, earning not only renown but the favour of the beautiful Lady Helene, whom he soon married and had a child with.
Still a boisterous Knight Errant, Leofric was called to duty by Louen Leoncoeur, fighting in the Errantry Wars against Archaon and the defense of The Empire. It was at Middenheim that King Louen led a hundred Knights Errant in a charge which faced Archaon and his legendary Swords of Chaos. Leofric rode in that charge, and although the young Knights Errant fought bravely, they were no match for the greatest warband of Chaos Knights. He and the King would be among the only survivors of that skirmish, although the battle was eventually won and the forces of Chaos driven off. Leofric was gifted with a mighty warhorse called Taschen, a reward from King Louen himself, as well as becoming a full Knight of the Realm.
Returning from the horrors of the North, Leofric was no longer the energetic young knight he once was, but a solemn and dutiful warrior of Bretonnia. He rode alongside his wife and child throughout Quenelles, visiting other lords and competing in great tourneys. It was one fateful night however when his wife disappeared at the border to Athel Loren, stolen by the Fay. The incensed noble set off into the forest to save his wife, only to be caught up in a war between the Wood Elves and the vile Beastmen of Chaos.
Striking an alliance with the Elves, Leothric would help save Athel Loren, fighting alongside Highborn and Forest Dragons to stem the tide of chaos. Eventually, he received a vision from the Lady herself. She alone knew how Leofric could be reunited with his wife, but he needed to prove himself pure to save her.
Leofric set off on the Grail Quest. He travelled far and wide, journeying to lost lands and encountering many strange and wonderful things. In distant Cathay he slew the Jade Dragon of the Emerald River and saved the wives of Emperor Zhang-Jimou from decapitation by the Executioner Cult of the Jade Pearl. The mysteries of far off Ind were laid before him as he quested for the Grail in the Caves of Fire and learned the secrets of the ancient beings who dwelt there. His quest drove him ever onwards until, at last, in the darkest place of the world, Leofric discovered the Grail and supped from its radiant waters as a hunter's moon rose over the forest of the Asrai.
Leofric would return to Athel Loren many times over the years, travelling its secret paths and knowing that one day he would be reunited with his beloved...
