Justice

Justice is the legendary sword of Artur Paendrag Tanreall. The blade is slightly curved and not heron-marked. The hilt is cloth-tied. Rand claims to Min that the sword is a power-forged weapon, although when he gives it to Tam he expresses uncertainty about the sword's status.

It was believed lost until 1000 NE. An excavation uncovered the sword under a submerged statue, but its true nature remained unknown. It was taken to Rand al'Thor, who recognized it immediately. Oddly, he recognized it from his own memories and not from Lews Therin's. This indicates it was present at Falme, when the Heroes of the Horn - and specifically Hawkwing - were called to fight the Seanchan. When returning to the vicinity of Falme to parley with Tuon Athaem Kore Paendrag, Rand thinks to himself that Justice reminds him of his previous visit.

He gave it to his father, Tam al'Thor, as a farewell gift before the Last Battle.

Interesting details

1. At the Last Battle there must have been two instances of Justice: one is with Tam and the other with Artur Hawkwing, summoned by the Horn of Valere.
   A figure rode through the mists at the front of the heroes. Tall and imperious, with a nose like a beak, Artur Hawkwing carried Justice, his sword, on his shoulder as he rode.

2. At Falme Artur wore Justice at his side. At the Last Battle on his shoulder.
   Tall and hook-nosed, with dark, deep-set eyes, his great sword Justice at his side.

3. Since it is not mentioned that Artur Hawkwing ever claimed himself to be the Dragon Reborn, it is odd that he wore a sword with a Dragon figure on its scabbard. One possibility is that he obtained the scabbard together with the sword. Given the Second Oath and the Dragon figure, it is likely that the pair date to the Age of Legends.

Quotes about Justice

The weapon was long, slightly curved, and the lacquered scabbard was painted with a long, sinuous dragon of red and gold. It looked as if it had been designed specifically for Rand – and yet it was centuries old, unearthed only recently. "How odd, that they should find this now", he thought, "and make a gift of it to me, completely unaware of what they were holding..."

He had taken to wearing the sword immediately. It felt right beneath his fingers. He had told no one, not even Min, that he had recognized the weapon. And not, oddly from Lews Therin's memories – but Rand's own.

Rand reached down, touching the sword he wore at his waist. It was the curved one, with the scabbard of black, painted with the twisting dragon, red and gold. For more reasons than one, it made him think of the last time he had been in Falme.

Rand put on his boots, then did up their buckles. He stood, reaching for the sword which leaned against his clothing chest. The black scabbard, with its lacquered red and gold dragon, sparkled in the light. Such a strange weapon those scholars had found beneath the submerged statue. The sword felt so old. Was Rand wearing it today as a symbol of something? A sign, perhaps, that he was riding to battle?

"I have to fix what problems I can," Rand said, pulling the ancient sword from the sheath and checking the blade. There was no heron mark, but the fine steel blade glistened in the lamplight, showing the undulating lines of its folded metal. It had been Power-forged, he claimed. He seemed to know things about it he did not share.

The cloth came off, revealing a majestic sword with a black-lacquered sheath painted with entwined dragons of red and gold.

[Tam] "Tell me, where did you get this weapon?"

[Rand] "I found it."

[Tam] "It's as fine a blade as I've ever seen." Tam pulled it out again, looking at the folds of the metal. "It's ancient. And used. Well-used. Cared for, certainly, but this didn't just sit in some warlord's trophy case. Men have swung this blade. Killed with it."

[Rand] "It belonged ... to a kindred soul."

[...]

Tam completed Hare Finds Its Hole, sliding the weapon into its sheath in one smooth motion. Orange lantern light reflected off of the blade as it slipped into its cover. "Beautiful," Tam said. "Light, the weight, the construction ... Is it Power-forged?"

"I believe it to be," Rand said.

He never had a chance to fight with it.
