Longwei Tang is full of dark magic and darker impulses.
Longwei obsessively loves his best friend, Jian Chu, when they are children in the orphanage. He worships Jian as he knows instinctively that Jian is truly good and true and strong. But he comes to realize that heros such as Jian do not come on top during their time with Feng Huo. Even more disturbingly, he finds that he excels at the darkest Chinese Sorcery that Feng Huo can show him. He comes to believe that it is better to be feared than loved. He uses that mantra to work his way, and destroy Feng, kill his way up the Chinese Triads and take what he wants. He forms his own Triad, the Heian Mofa, in a society not known for embracing new things or change. But he doesn’t care. It gives him a greater thrill to oppose the common understanding.
He may be behind the death of Freya Brand. She stood between him and opening a branch of his new Triad in San Francisco. He has no idea that she has such a bewitching son as Freyr until Freyr spots him using his magic to send yet another enemy into the grave. Though he could easily kill Freyr right then and there, he strangely decides not to. Instead, he makes the decision to let Freyr live with the threat that if Freyr reports what he has seen to anyone he won’t kill Freyr, but will kill everyone Freyr loves. He then demands that Freyr spend the night with him. He gives Freyr the most unforgettable night of pleasure.
When he realizes that Jian is interested romantically in Freyr as well, he becomes more interested in keeping the young man for himself.
