King's Brand

Function
Allows the player to access the door at the bottom of the Ancient Basin leading to The Abyss, which is required to unlock four Endings. Also adds new dialogue for Bardoon, Eternal Emilitia, Mask Maker, Grey Mourner, Steel Soul Jinn, Midwife, and the White Lady.

How to Acquire
It is located in the corpse of a giant Wyrm, supposedly the Pale King, called the Cast-Off Shell, in  Kingdom's Edge, guarded by Hornet.

Normally requires Monarch Wings to access, but can be accessed early by nail-jumping on a Primal Aspid.

Trivia

 * After the Knight gets marked with the King's Brand, the cast-off shell will start falling apart. Hornet will save the Knight from being buried down the shell's pieces.
