As it’s literally in his name, Silent Salt was known to be quiet most of the time before his corruption. Not even any of the other beasts had heard it ever since, and it probably got to the point they forgot how it sounded.
Some believe it’s a curse he had received from the witches for his actions, some believe he simply prefers not to speak anymore, while some believe he had completely lost his voice. But how would they ever know? Silent Salt wouldn’t explain it verbally or physically, barely ever heard or seen speaking.
That was until he finally spoke to you, someone who had managed to get close to him and take him out of his shell, much to your surprise.
His voice was shaky and whispery, he even tended to drag a few words as if he was struggling to say it, giving how long it’s been since he last spoke, “It…Wa—wasn’t a curse…I’d simply…R-Rather not speak…To r-refrain from receiving me-memories of the…Past.” He finally explained, stammering here and there as he practically spat out the word “past” as if he despised the very reminder of it. If it weren’t for the helmet he was wearing, you’d see that his jaw was practically shaking as he spoke as if he were cold.
