The Nameless Lord

The Nameless Lord is the supreme Die of Heaven and the one whom the Angels and Archangels serve. He may be encountered in Paradisio, but he is known to only appear before beings of the highest virtue or those possessing the grandest of souls. 
The first time he was encountered by Ib was during the War on Heaven, mere moments before Heaven's Fall:
It is written that Emperor Letolux Regalin along with Umbran Occidis Bonagrim and Warchief Aximar Heartripper were the only surviving members of Heaven's Assault to reach Paradisio. They had desperately ascended through the branches of Yggdrasil as Heaven's Armies pursued, slaughtering all their followers who willing made the ultimate sacrifice so that they might complete their unholy mission, and the moment that they set foot upon Cloud One, they sensed an overwhelming presence all around and inside of them. It was then they all dropped to their knees and bowed their heads as their eyes overflowed with tears. In unison, they spoke, "Forgive us, O Lord, for now that we have borne witness to your glory, we have realized the error in our ways."
And The Lord spoke, "Take heart, for all your sins will be forgiven. Now, reveal unto me your transgressions."
The Emperor spoke, "We, in our arrogant pursuit of earthly dominion and accolades, rejected the guidance of Heaven, damn our kind from ever achieving true paradise as this on Aum. Our wicked and fragmented lenses through which we behold this immaculate land would shatter if not for Your divine good."
The Umbran spoke, "We, in our innate hatred for all things that are holy and our primal envy of immortality and beauty, convinced ourselves that the good of men is not the good of the world. Were it not for your tender mercy and judicious forbearance, our vile lips would not have been tolerated to utter even one word of our wicked schemes to conspire against You and Your order."
The Warchief spoke, "We, in our veneration and deception of ourselves, knew that our unpure hearts might falter when faced with the unmitigated magnificence of the eternal. We cursed ourselves in our pathetic despair and without Your hallowed eminence, we would beyond all hope. But all these things and more were already known unto you, O Lord."
In their shame, the three of them disrobed to reveal the runic scars that they had engraved across their flesh. They were wholly covered in the sigils of the Abyss, carved into their now rancid and rotted skin all the way down to their bones. Beneath their glamored armors, they were weak and emaciated. They reeked of sulfur and brimstone and they had allowed their souls to be corrupted with an evil greater than even the most sinister of Archdemons. 
And The Lord spoke, "Fear not, for all your sins are forgiven."
The wounds on their bodies began to reseal themselves until any semblance scars had vanished, and their flesh was pristine once more.
The three of them wept once more their voiced called out in harmony, "You must not-"
But The Lord interrupted and spoke "It is done. It was by your will that you came to enact your devious scheme and it is by my will that it shall succeed. Go now and I shall grant you safe haven on Aum, but now Heaven will fall."
And it was so.
