From publisher blurb:
The binder is a band new class which lets you redefine your playstyle each day by attuning to the spirits of dead gods and heroes. These spirits from the past, called vestiges, afford their own features and traits, and each has a backstory all their own, drawn from the margins of world mythology. Their revisionist stories shine a light on tragic tales from across time, and ground the binder's personalities in genuine myth. The Complete Binder further expands the class's options with a plethora of variant rules, brand new subclasses, and even more vestiges to experiment with. If you want to play a character that can truly slide into any role, the binder is the class for you!
