Gromolus Three-heads

From the introduction:

Long ago, the Aurumel Skyborn Gromolus Three-Heads was disgraced before the Houses of Veile after being convicted of the murder of both of his influential parents. They had attempted to commit Gromolus to the ranks of the ‘loyal’ Aurumel Skyborn, who rotted away within the Black House—a large and infamous circle of atrophied Skyborn that serve the more tyrannical Aurumel Houses of Veile. He could not bear this life-crushing fate, so he cut down his parents in their beds.
