*Rubrum Trivia*
If one were to talk about the martial arts and technique of the High King Marcius of the never-ending empire of Solas, one should take great care to include one of the few preferred techniques of the High King, the 'Great Thunder Doom.'
Records told a story that the Great Thunder Doom was a technique derived from the High King's transformation of the 'Storm Dragon God's Descend.' Being just called the Storm Dragon God's Descend together with the thunderous transformation at the beginning, the Great Thunder Doom gained its signature name after the High King managed to develop further diverse techniques derived from the Storm Dragon God's Descend transformation.
Just as the transformation of the Storm Dragon God's Descend was the result of fusing the partial transformation and beast soul techniques, the Great Thunder Doom also boasted the destructive prowess of the partial transformation and overwhelming spirit energy of the beast soul.
