Just left this as a comment on WP's newest vid. Just my thoughts on the plot build up.
Kuunavang is the champion of the Deep Sea Dragon. Deep Sea Dragon's domains of power are life, and torment. It was hibernating in the jade sea when it became jade. There is a large underwater channel that connects the jade sea with the rest of the ocean. This channel probably goes through/under the Kaineng City area. When it awoke, and was finally freed by the jade slowly turning back to water it swam out to explore. Scaring a lot of beings during it's swim. The reason it wants to take action now is because a showdown between Jormag, and Primordus may be inevitable. It knows such a showdown will not end with a death of a dragon, but a birth of another water dragon. A completely fresh, choatic, hungry, and unsympathetic water dragon. Also just my best guess here Deep Sea Dragon's name is probably gonna be some variant of Saburou, or Seiryuu. With the names of the original being Seiryuu, and the copy will be Saburou respectifully.
Also Seiryuu may be self hating anti hero. It has lived a life tormented by it's own powers of torment. Finally realizing that life is a cycle of tormant, and solace. Sacrificing itself, and forcing Saburou into the same. The body mass, and combined powers are used as the one, and final strike to kill Primordus, and Jormag while the two are fighting, or mating again.
To add to this Kanaxai from the Deep is the result of Seiryuu's domain's of power subsciously at work while it slept. Seiryuu created a life, and tormented it into uder madness during the process.
