Yevhen is a dwarven merchant and member in good standing of the Dwarven Merchants' Guild. He is the father of Merin, Emrys, and Iwan, and the employer of Dera, an elven woman who raised his sons after his wife died.
Yevhen is involved in the quest Fool's Gold.
Yevhen desperately asks Hawke to retrieve his three sons who have gone down into the Deep Roads, by themselves, in search of treasure. Once down there, Hawke will find Yevhen's eldest son, Emrys, sitting in front of a locked door. He will explain that his younger brother, Iwan, locked the youngest brother, Merin, in a room full of darkspawn before scampering off to find the treasure. Hawke then tells Emrys to go back to his father and must now choose which brother to save. If Hawke goes around the locked door and goes to the room Merin is locked in, Hawke and company must help him fight off a small troop of darkspawn. This act will save Merin who will then go back to his father. However, doing this will result in Iwan's death. Alternatively, Hawke can by-pass Merin's tomb and run straight to Iwan. Helping Iwan fight off his darkspawn will result in Merin's death.Upon returning with only two sons, Yevhen will be devastated. If Merin is the one who perished and Yevhen is told the truth (that Iwan locked him in a room full of darkspawn in order to get the treasure), Yevhen will become enraged and banish Iwan.
