Romulus's Links
Being raised by Synotra after Loki left, Romulus is solely devoted to the Hakaoh kingdom. He has adopted his mother's morals and beliefs that his father was a low-life degenerate who had started the war, and as such, holds a deep-rooted hatred for both him and Sigyn.
Loki hardly knows about Romulus' existence. It was mentioned by King Avel that he and Synotra were to raise a child from the royal hatchery, but Loki left before the plan could go through and anything else was decided.
