un:mute - Starting life as an OP mute!

Hai Petelunica, a runaway, stumbles across a clearing in a forest one day: with a glowing light blue sword submerged within it. An old man appears behind him, congratulating him that he was 'worthy', it's the most mana he had ever felt from a sword. The only catch being... The wielder is unable to talk for the rest of their life.
