And a second submission. We need more swords. We ALWAYS need more swords.

[b]World of Origin:[/b] Dark Souls
[b]Personality:[/b] Artorias is a brave and honourable knight with a persistent hatred for the servants of dark--which, regardless of wider morality, seem to entirely be insane or sociopathic [i]and[/i] homicidal, as well as destructive. His willpower is as renowned as Artorias' ability with a sword, never breaking as far as anyone has ever known--the one exception being the person who eventually killed him, someone he wanted to warn away. He's also selfless enough to sacrifice his only defence and get injured in defence of Sif.
[b]History:[/b] One of the Four Knights of Gwyn, Artorias was a general in the war against the immortal dragons. After winning the war, the knights more or less spent their time killing the remaining dragons (to the point their captain did it as a hobby). More than five hundred years after Gwyn set himself on fire, the rulers of New Londo made a pact with the Abyss... which began to devour and consume their citizens. Artorias himself made a pact with the beasts there, gaining a ring that would allow him to traverse the Abyss without melting instantly, in order to kill the life-stealing Darkwraiths.
After the crisis was contained, Artorias was awarded his pendant, and a similar problem appeared in nearby Oolacile. He set off to rescue the princess and broke his arm in the process, leaving his shield behind to guard his companion even as the Abyss began to corrupt him. Defeated and broken, he turned into a mindless beast, barely holding on but still fighting  his enemies... until an undead from the future came back and allowed him to die with honour.
Of course, that hasn't happened yet. Or maybe it has, time flows strangely in Lordran...
[b]Abilities:[/b] Unmatched with a sword in his home, Artorias has enough strength to wield his blade with his off-hand alone. His sword, now cursed, cuts as much with magic as sheer force and possesses the ability to cut through ghosts and their ilk, even though they have no physical form. His other possessions are a shield where the wielder is more likely to buckle than it is to get scratched, a ring that allows him to traverse the Abyss, another ring to supplement his unbendable will, and a pendant that can repel dark magic (as well as his armour). It's also quite plausible that Sif, his companion, would be with him--essentially a human-sized wolf pup.
[b]Other:[/b] He's something like ten feet tall.[/hider]
