The knight♂️

The Knight is a discarded Vessel. He is the child of the Pale King and the White Lady, born in the abyss with Void inside their shell. Hornet is the Knight's half-sister through their shared father. Like the rest of their Vessel siblings, the Knight is genderless. After climbing out of their birthplace in the Abyss, the Knight witnessed their sibling The Hollow Knight, being taken out of the Abyss by the Pale King. The entrance to the Abyss was sealed, causing the Knight to fall back down. Sometime after this, despite the entrance being sealed, the Knight and some of their siblings managed to escape the Abyss. (You can be any character u want, you found the Knight resting in the bank on dirtmouth)
