Silver Sword of Gith

The Silver Sword of Gith was a magical sword and an artifact sacred to the githyanki. It was the first and most powerful of the silver swords and belonged to the gith hero and namesake Gith.

Description
The Silver Sword of Gith appeared to have a wavy, jagged-edged silver blade and a golden hilt. It weighed. Although reforged in 1374 DR, several pieces remained missing and these appeared as gaps in the reformed blade, with a ghostly outline to mark where they should be.

History
According to legend, the silver sword was originally forged by the mystic Zerthimon, who gave it to Gith, leader of the rebellion of their enslaved race against the illithids. She wielded it much in their battles against the mind flayers. But after their liberation, Gith and Zerthimon came into conflict over the future of their race, which in turn split into the githyanki and the githzerai. Gith took the Silver Sword with her, and the silver swords of the githyanki were likely based on it.

When Gith ventured into the Nine Hells to seek an alliance with the red dragons and never returned, the Silver Sword was lost.

The blade was determined to be the only weapon powerful enough to defeat the ancient, corrupted Guardian of Illefarn. The warlock Ammon Jerro learned of the weapon from his dealings with the githyanki, devils, and an ancient crystal dragon named Nolalothcaragascint. He ultimately found the artifact but when he attacked the King of Shadows with it in battle in West Harbor, it shattered into dozens of shards, one of which buried itself inside the body of a baby who would grow up to be called the Kalach-Cha—"shard bearer" in the Gith language.

The slaad lord Ygorl also desired the artifact to increase his own power. At the time, the sword was in the hands of Cireka, a githyanki general. The two battled over it, pitting their armies against each other until their fight spilled over into Toril and Khelben Arunsun trapped them in a magical stone. When adventurers released the two in the, their fight resumed until Cireka was slain by the red dragon Caminus. Rannek of Nesmé retrieved the blade and used it to help defeat Ygorl. He was concerned, however, that the githyanki would return to retrieve it at some point.

In the, the Kalach-Cha collected the scattered shards, whilst being pursued by the zealous githyanki, and eventually reassembled them at the site where the blade originally shattered. The sword gained a couple of new powers, owing to the fractured nature of the blade, but since the final shard was still buried in the Kalach-Cha's chest, it could not be fully restored. The nevertheless powerful blade was then used to finally defeat the King of Shadows.

The Silver Sword, in addition to being an outsider-slayer of unimaginable power, was the key to the Betrayer's Gate, a portal to the Fugue Plane located in a temple to Myrkul on the Plane of Shadow in Mulsantir. This Gate was used by Akachi the Betrayer, a former priest of Myrkul, who used the blade to try and destroy the Wall of the Faithless and free his dead love, a Red Wizard. After the Kalach-Cha was abducted into the land of Rashemen by the Founder after they vanquished the King of Shadows, the prime shard that was buried in their chest was torn from them violently. The Founder then recast the whole sword with the missing shard, strengthening the weapon even further, though the blade retained its previous nature of servitude to the Shard-Bearer who reforged it. The Founder then explained her reason for choosing the Shard-Bearer to defeat the spirit eater, "Because you had the will to master the Blade of Gith." After regaining the Blade, the Shard-bearer then used the weapon to open the Betrayer's Gate. When they reached the Fugue Plane and Kelemvor's Gray City, the Kalach-Cha was given the choice of either leading Akachi's generals to lay siege to the City, or defending it against them. Whatever the Kalach-Cha decided, the Lord of the Dead, Kelemvor, arrived and allowed the Shard-Bearer to claim their soul from the Wall of the Faithless, where the Founder and Akachi once were. The Shard-Bearer had to then battle the avatar of the Spirit-Eater curse for control of their own soul. Eventually, after battling the Spirit-Eater curse across dreamscape versions of Crossroad Keep and West Harbor, the Kalach-Cha cornered the avatar and used the Silver Sword to defeat him.
