Silent Salt Cookie

for some odd reason - after corruption he dismissed his will to speak.

his cape is torn, but he also wears shoulder pads and a shining thing around his neck, probably also armor.

he is a knight-like appearing, so makes sense he got a dark sword.

he is a "fallen hero" aka the "beast" so it makes sense for him to be evil and genocidal due to his sword and armor. once a cookie of solidarity now of silence. He is quite uncaring and often selfish due to his corrupted state.

Silent Salt Cookie appears to correspond to the Land of Silence/Black Salt Flatland region of Beast-Yeast.
