He is dark-featured and handsome, and his heritage is partially Turkish, according to him.
Tomas and Dhiar met when Tomas had been singing in one of the many underground clubs enjoyed by Chana, primarily for their serving of alcohol. Dhiar and Tomas had a fun time at the Turkish baths nearby, and later Dhiar introduced Tomas to Merry. The two hit it off and, when Dhiar departed for Berlin, the two continued to deepen their relationship.
When Dhiar returned to their city, by the time he departed again, Merry and Tomas were decidedly together in a relationship.
