Emrys Perdue's Links
Emrys and Karmos are married- although, ironically enough, Emrys thought Karmos hated him when they first met. Emrys continuously tried to get Karmos's approval, and the two grew closer, eventually becoming best friends. Then, while pouring over research books in order to help his brother, Emrys came to the realization he had feelings for Karmos. After the war, Emrys and Karmos retired from adventuring and moved in together, coming up with a 10 year plan. This plan went out the window after Wyn's death, and the two of them got married far sooner than originally planned. Emrys is completely devoted to Karmos and would do just about anything for him.
Considering the two are both married to each other, it's safe to assume that they at least tolerate each other. Since they first met, Karmos knew that he would like Emrys--he was so heroic and caring, who wouldn't like him?--but he truly fell for him when Quirkilxa, his niece, call Emrys "Uncle Perdue". While the two eventually became best friends through the course of the campaign, Karmos tried to keep his distance from the other, not wanting to mess with the relationship Emrys had with Magenta. Eventually, they finally addressed their feelings for one another in the last battle and were able to care for one another after the war. The two settled down with each other on a farm with a large cattle of dogs and cats, and while Emrys ended up proposing far earlier than planned, Karmos knew that he was the love of his life and would've wanted to grow old with him anyways.
