Skarde Troelson is a Viking who is mentioned in the game Dragons: Titan Uprising.
Skarde Troelson spent his entire life studying Triple Strykes and their behavior. He came to the conclusion that a specific ritual could be performed in order to have the power of a Triple Stryke transferred to the worker, specifically Deathstalker. During said ritual, a brew made from certain herbs known for their mystical and anesthetic properties, is sprayed into the face of the Deathstalker in order to appease it and make it amenable to the influence of the person working the ritual. Troelson wrote down the ritual in a book he titled "The Book of Thorns". He subsequently disappeared in the northern lands, a territory known to be inhabited by Triple Strykes, presumably to perform the ritual. He never returned, leaving other Viking to believe that he either failed and was killed or he succeeded and left the archipelago for good.
