Vestige
Vestiges are weird super-ghost things from the later fluff of Dungeons & Dragons 3.5 edition. Specifically, these are the metaphysical entities that the Binder class calls up and allows to timeshare their body in exchange for various magical powers.
List of Tome of Magic Vestiges
This was the big array of vestiges that appeared in the initial Tome of Magic.
Acererak the Devourer
The Demi-Lich who created the Tomb of Horrors.
Agares, Truth Betrayed

Amon, The Void Before The Altar
The corrupted essence of a once-goodly god.
Andras, The Gray Knight
An Elf who served for centuries as first a paladin and then a blackguard before giving up on both sides in disgust.
Andromalius, The Repentant Rogue
A chosen of the god of thieves, Olidammara, who repented on his deathbed, hoping to play the ultimate trick and steal his own soul away from his god. It worked too well; his god approved, once he realised the joke, but he couldn't take Andromalius back without wrecking the joke. So he made him a vestige instead.
Aym, Queen Avarice
A corrupt dwarven queen who destroyed her own kingdom through her insatiable greed.
Balam, The Bitter Angel
The despondent spirit of a slain angel who was set an impossible task - purportedly ending the practice of humanoid sacrifice - that failed and claimed her life.

Dhalver-Nar, The Tortured One
A human who is believed to have pioneered the art of binding, most known for his obsession with teeth. Seriously, he manifests as a human man with gums instead of skin and teeth everywhere, even for fucking eyes. That's just not right!
Dantalion, The Star Emperor
A gestalt consciousness born from the ancestral spirits of a now-lost royal line.
Eligor, Dragon Slayer
A dragon slayer of such proficiency that Tiamat demanded his soul be given to her after his death, threatening to set her dragons on the mortal races and forcing the gods to surrender him. She then raised him as a dragon-revering blackguard and used him as her own mightiest champion; after he got killed again, nobody wanted to touch his soul and so he became a vestige.
Eurynome, Mother of the Material
A titan who created the physical world by separating the sky and sea before being slain by the gods for daring to steal into the world as yet unformed, with her body becoming the land and her blood giving rise to all animals.

When Thrym sought her ought, and beheld both her true ugly form and the monstrous twin sons she had born him, he turned them into the first minotaurs and spread the creedo of distrusting all beauty to the frost giants. In her shame, Haagenti was unable to rest in any of the planes after her death.
Halphax, The Angel in the Angle
A gnomish master engineer who created an inescapable prison-city at the behest of hobgoblin conquerors to try and save his wife's life, ultimately costing the lives of thousands of his fellows.

Hextor murdered Savnok by stealing his mother's bow and arrows and bleeding him to death with dozens of shots, after which the brothers hid Savnok's soul where no god could find it and returned the armor, bow and arrows to their rightful place, covering up the crime.
