Thallan was an only child to the Lord and Lady of Malwyrth, his family estate. He was spoiled as a boy. His mother, Elasha, doted on him and still does. He got her skill of acting and pretending, while he got his father Fenian's self-sure attitude. As a boy, he was very close to his mother, a fact his father berated him for. His father would call him a weak suckling, a mama's boy. But this was only the beginning.

Fenian had a temper and he tended to take it out on his son and wife. One night it had gone farther than it ever had before; Elasha was knocked unconscious on the floor, and Thallan, in a burst of anger, killed his father.

Elasha did eventually wake up, and when she did Thallan released just exactly what he had done, and so with his mother's help, they erased all evidence of how Fenian died. They pointed the murder at one of Fenian's personal servants and had the servant executed for it and they mourned the appropriate period and moved on with their lives. They are the only two who know about how Fenian of Malwyrth truly died, and they don't plan on ever letting anyone in on their little secret.

Since his father's death, Thallan took on Fenian's roles around the house, stepping into the role of Lord of the house. He is still very close to his mother and he does everything in his power to make sure she is happy.
