Gyx

Prerequisite: bound to at least one other vestige

Heretical Lore

You have advantage on ability checks you make to recall legends, myths, or lore. Additionally, the GM can allow you to make such checks, even when it would be impossible for you to know such information.

Strength in Numbers

While bound to Gyx, you gain a bonus to your vestige save DC, spell attack modifier, and any weapon attack roll you make that uses your Charisma, instead of Strength or Dexterity. This bonus is equal to the number of other vestiges you have bound and doesn’t stack with bonuses provided by magic weapons or items.

Legendary Vestige

If a creature succeeds on a saving throw against a spell or feature offered to you by one of your vestiges, you can force that creature to reroll the save, and it must use the new roll. Once you use this feature, you can’t use it again until you finish a long rest.

Trait: Hidden

While bound to Gyx, you can cloak your vestiges with ease. You can suppress or reveal any of your vestiges’ traits once on each of your turns (no action required). Moreover, you can instantly tell when another creature is bound to vestiges, and the number of vestiges to which they are bound. You have advantage on attack rolls against other creatures bound to vestiges.

Gyx, the mother of binding, offers no power of her own but lets you fully seize the might of your other vestiges.

Legend

The first binder, Gyx, had no ambitions of founding a religion or pioneering a new form of magic, no matter what her later followers might claim. Instead, she stumbled upon the existence of vestiges quite by accident when her scrying spell malfunctioned. As often happens when this spell fails, Gyx heard a whoosh of static and saw a flash of deep black. But on this occasion, she heard a whisper in the noise.
Through experimentation, she refined the spell into a rudimentary binding ritual and communed with the distant spirits of the Void. They had always been there, just out of earshot, just beyond the limitations of sight, only Gyx had learned to look for them. She took fastidious notes on anything the fleeting voices told her: their names, their symbols, all they could remember. Many of them possessed names recorded in history books or spoken of in temples, but these voices were different and told stories of hardship and heartbreak, not of glory and triumph. She collected these tales of the forgotten dead gods and heroes in a tome, and printed ten copies. These books would go on to inspire legions of binders, as well as others who would brand them heretics.
Gyx’s final story, however, she took to grave. It was a collection of all she learned, a succinct tale now told only by her vestige: In the beginning, there was Void. Then one great sin. In the end, there shall be Void.
