Heinous is a former Dread Emperor mentioned in the Scroll of Vainglory, thirty-ninth of the Secret Histories of Praes. The text in questioned was destroyed by order of Dread Empress Maleficent II, and only partial texts remain. This, combined with the fact that he said to have declared war on Keter, imply that he was one, possibly the first, of the Dread Emperors during the Secret Wars. If so, his reign was approximately somewhere in the span 600-650 years before current events.
Quotes and epigraphs
