Silent Sven, also known as Sven, is an apparently mute Viking shepherd on Berk. Until, of course, he "broke his silence".
Silent Sven's chest hairs were burned during a Screaming Death practice drill, in "A Tale of Two Dragons".
Sven then became frustrated by Stoick's complaining about the arrangements of the armory's weapons in the episode, "Crushing It". However, Sven was threatened by Stoick when he did not arrange the weapons the way Stoick wanted it. Sven then left to tend to his sheep.
Sven joined the Dragon Riders' Auxiliary in "Team Astrid", taking a Monstrous Nightmare, named Sven's Nightmare, as his dragon in order to defend Berk. He then assisted Astrid, Stoick and the other riders in defending Dragon's Edge from Dagur and his Berserkers.
Sven appears during Berk's 400th Anniversary celebration in "Midnight Scrum". Hiccup sees three men that look suspicious and confronts them, only for them to be Sven's uncles visiting: Whispering Waldo, Soft-Spoken Sam, and Mute Marvin.
Sven also makes a brief appearance in the episode "The Longest Day" when Gobber points out how the 24 hour sunlight affects the Hooligan villagers. He points at Silent Sven who is dancing with one of his sheep. Hiccup says that actually isn't so unusual for Sven.
In the episode "The Wings of War, Part 1", Sven appears along with Spitelout, Stoick, and Gobber in a Berk Council meeting about how best to deal with the Dragon Flyers that have taken over Dragon's Edge.
After he broke his silence, Sven's new voice scared the sheep out of the pen.
While Sven does not appear in the game, his farm is a part of the "Call of the Death Song" expansion pack. An invading Death Song makes its nest there. Sven's account of the Death Song appearing on his account is detailed on the website for School of Dragons:
|“|| Sven looked out at his farm with pride. It was true: He had the best farm in all of Berk. With its flourishing crops and fattened livestock, no one could compete with Sven’s farm.|
His admiration was cut short, however, when a large shadow fell over him. Sven frowned and scratched his head. It was noon, and certainly not time for shadows this big. Then, with a loud splat, something orange plummeted from the sky and landed right on his crops. Sven shrieked and jumped back, turning his face towards the sky to see who had the audacity to sabotage him… What he saw made his heart stop.
A large, beautiful dragon with resplendent wings circled above him. Even with the sun glaring in his face, Sven knew exactly what he was looking at. The dragon reared its head back and spit out another enormous glob of the amber-like substance.
Sven jumped out of the way, just narrowly avoiding getting hit. While he wanted to stay and make sure that his farm wasn’t destroyed, he knew that he had to get to the School of Dragons. The Riders of Berk would know what to do. All he had to do was leave calmly and not draw any attention to himself. As he slowly stepped back, the Death Song looked directly at him, its pupils dilating dangerously.
All thoughts of remaining calm were forgotten as Sven let out a choked gasp. “D-D-D-Death Song!” Sven screamed as he took off towards the School of Dragons.

Sven is also mentioned in the School of Dragons Stable Quest called "Slice and Dice", in which he needs dragon help clearing trees for a new farm.
Silent Sven gets a cold, complete with a sore throat. Gothi crafts him some medicine, but needs one particular ingredient and sends Gobber out to retrieve it from Healer's Island. The last ingredient is the saliva of the Quiverpain. Gobber is ultimately successful, and Silent Sven thanks Gobber for assistance healing his sore throat.
Sven wears a light brown sleeveless leather tunic and has thick bushy grey eyebrows. He is bald and has a neat blonde mustache that is braided at the tip. He is sometimes seen with a spear-like weapon.
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. He also seems to have no tolerance for disobedience from his sheep and cared deeply for his prized black sheep. He seems to think of his sheep as his children, as he was complaining to Stoick about them ruining his house and not listening to him.

- Despite appearing in "Viking for Hire", he was left unnamed until "A View to a Skrill, Part 1".
- His nickname might be a reference to the fact he is usually just a background character with no lines.
- He shares the same name as another resident of Berk, Sven, who is voiced by Brook Chalmers.
- In the first two seasons and Dawn of the Dragon Racers, Sven's tunic has stitching. In Dragons: Race to the Edge, it doesn't.
- According to Ruffnut Thorston, his wife has a fish-gutting station, mentioned in "Snotlout Gets the Axe".
