Silent Sven

Silent Sven, later known as Not So Silent Sven, is an aparantly mute Viking sheperd on Berk.

In Defenders of Berk
Silent Sven fought off the Frozen Skrill when he tried to eat his sheep herd. Sven then broke his silence to complain to Stoick the Vast about something in berk.

In Dawn of the Dragon Racers
After he broke his silence, Sven's new voice scared the sheep out of the pen.

Appearances
He is bald with a blonde mustache parted down the middle. He wears a tannish-brown shirt and and some green pants. He does not talk at all and that's why he is called silent. His hair actually got burned down by a trained dragon in one of the series.

Personality
Not much is known about this viking, but he seems serious and grumpy and dislikes it when people mess with his sheep and think he's deaf.
