The Vessels are genderless beings of the Void who were created by the Pale King as a means of stopping the Infection. They are described as the progeny of the Pale King and to be the spawn of the White Lady, containing the “soul” of the two beings. The area within the Abyss known as the Birthplace is assumed to be the location as to where the Vessels originated from. The Abyss is where most of them were discarded following the Pale King’s search for a pure Vessel.

Eventually, one Vessel was judged to be pure and was chosen to seal the Radiance within itself. This Vessel was named The Hollow Knight.

The Siblings found at the bottom of the Abyss are implied to be the Shades that originate from the shells of deceased Vessels. From this enemy and the boss Lost Kin it can be interpreted that all Vessels are related to each other or at the very least related to The Knight. Hornet calls the Hollow Knight the sibling of both her and of the Knight, further suggesting a sibling relationship.

After the Hollow Knight was lead out of the Abyss, the Pale King sealed the Abyss with a seal that could only be broken by somebody with the King's Brand, locking most of the other Vessels inside. Several Vessels managed to escape from the Abyss, including The Knight.
