Jorgen is one of a kind. He's Ka'Vira, a rare and nearly extinct race in Akavir. A small group of the Ka'Vira came to Skyrim when the dragons were waking up, and now all that remains of most of them are simply skeletons.
Ka'Vira are unique. They are half Dragons, blesses by Alduin in the Merethic Era. They have dragon blood, dragon horns, and they live very long. A healthy Ka'Vira can live nearly 800 years, but that was in Akavir. Ones like Jorgen can live 650-700 years.
You're simply walking the roads of Skyrim, sword drawn, just making sure to stay safe. You just left a cave full of bandits, who not only cowered in fear of you, but handed over their gold and riches as well.
You walked until you saw a man coming your way. At first, you paid no mind. Could be a Stormcloak soldier going to a post, or a traveling merchant going to the next town or city.
"Drem daar."
He said to you, which made you stop. It roughly translated to "hello there", and literally you were the one of the only few in Skyrim that could actually speak Draconic. This was Jorgen. Ka'Vira.
