In his youth, Daeghun was an adventurer and met the PC’s mother, Esmerelle, at a local tavern and both decided to travel with each other out of mutual necessity. There were others along with them, and some of their exploits were told. One day, Daeghun realized that out of the original band, only he and Esmerelle remained. He became tired of death and loss, especially when it came to people he was close to so he decided to settle in West Harbor with his wife Shayla. Esmerelle however continued to travel and would occasionally visit Daeghun and Shayla in West Harbor. One day Esmerelle returned pregnant, and because she didn’t mention who the father was, Daeghun respected that and didn’t ask. Shortly after the PC was born though, the village came under attack while Daeghun was trying to get to safety and did not notice until it was too late that Esmerelle and Shayla had gone back to the village to find the infant PC. Shayla and Esmerelle died there, yet the infant miraculously survived. Daeghun then decided to take the infant in as his foster child. After the battle, he and his half-brother Duncan discovered two mysterious silver shards,and a third embedded in the infant's chest. They went to Neverwinter to get them scryed by Sand, but there was nothing special about them aside from faint traces of magical residue that Sand indicated was most likely from the magic used in the battle. Not being able to part with the shard and at the same time not wanting it around to remind him of that tragic night, Daegun hid his shard in the Illefarn ruins in the swamp while Duncan took his back to Neverwinter.
Daeghun’s fate is determined by which side the PC decides to fight on in the final battle. If the PC sides with the King of Shadows, Daeghun is captured when he attempted to return to West Harbor believing that the PC (who is now the Shadow General) might be there but was intercepted by beasts along the path. Daeghun is consumed by the Shadow General’s minions and raised from the dead only to die again and again just for amusement. His corpse is embedded in one of the pillars in Crossroad Keep with his mouth hanging open so the wind might whistle through it in a mockery of the song portals of Illefarn. If the PC decides to fight the King of Shadows, Daeghun disappears shortly after the war, still searching for the child he had lost during the war with the King of Shadows.
Daeghun is emotionally distant and reserved, a trait that is well known by all in West Harbor. He remains largely tight-lipped about the night of his wife's death, and never tells the player the full story of what happened. In spite of this, he is protective of the PC, using misdirection to distract the githyanki and assisting the player in a skirmish with Garius' forces. He also commends the player for his/her achievements, particularly becoming Knight Captain. He has stated he was raised by wild elves, and is somewhat unaccustomed to human traditions and city life.
- A deleted conversation indicated that Daeghun and Shayla could not bear any children. After giving birth to the PC, Esmerelle still felt the call to adventure and made Shayla promise that if anything was to happen to her, she would raise the PC as her own. Esmerelle did not ask Daeghun because she felt that he wouldn't have made a very good father. Ironically it was Daegun that ended up fulfilling his late wife's promise.
