Malia was said to be the spitting image of Count Halon Hasker, her father. They were both cold and aloof, perfectly suited for the military, where emotions can put you in danger.
The military after all faces enemies every day. Even if they don't, they need to be alert and not be distracted by other affairs.
The Hasker family is considered as a pure military family. In its long line, there were never court officials that appeared in their house.
The noble houses not just serve as lords of the land. Their members serve in both military and political systems of the kingdom. There are some houses that were well suited for military, while some were suited for court politcs.
The Hasker family belongs to the military and they were not alone in that way. Even the Frostwolf family belongs to this category. Magnus's siblings are now serving in the military after they completed their five-year course at the academy.
