Silent Salt Cookie

He is silent

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

Silent Salt Cookie wears a fully face hiding helmet with obscured vision element of 2 straight lines going upside down with a purple color

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

has a big ah sword

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

personality

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.

where is he?

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