The Company of the Shadowed Moon charged out of Deep Mountain, subduing and taking Aphoreth hostage despite the patrol of Silvery Host scouts that jumped to their Captain’s aid. While Captain Aphoreth didn’t survive the question at sword point, he did relay quite a bit of information to the party:
The Archangel Ilythramaxen once fought for his god during the Dawn War against the Primordials, but his god was slain and rubbed from existence, so powerful, so willful was Ilythramaxen that he took his remaining angelic hosts and fled the now burning realm of his god, swearing vengeance at any cost upon the primordial Imix who slew his master. This was ages ago, during was is known now as “The Astral Wanderings” the Archangel collected others to his cause of revenge, other angels who had lost their lords of whom there were so dedicated to.
The Archangel Ilythramaxen found through during the “Wanderings” that there was a place a void in the heavens above the Prime Material Plane that held the world of Toril; this would be a place that with sufficient preparation a singular attack could be launched into the realm of Imix the Primordial of fire, the Primordial who had destroyed the god that Ilythramaxen had served with so much fervor.
The Archangel had his scouts explore this void above Toril, and they found the perfect piece of ordinance to send through into Imix’s realm, the 19th hidden moon. However the moon was “inhabited” after a fashion, the gnomish god Nebelun the Meddler was here, possessing the form of an avatar, crafting sentient golems from the metallic sand, melting it down and forging a race that he hoped would be both inquisitive and cunning, worthy allies for his gnomish followers.
No other moon would serve the purpose the Angels were planning, they waited for their moment to strike, and they found it, during the Time of Troubles. The gods were cast from the heavens suddenly and in the moments when the Avatar of Nebelun realized he was now barred from his realm above in the Astral Sea, the Angels struck at him.
Many of the Silvery Host were destroyed trying to tame the Avatar of Nebelun, but eventually Ilythramaxen managed to harness the god’s spirit and entrap it within “The Silent Keystone”, an object of great power from another realm, the keystone trapped the god for the most part, but it could not contain quite all of his essence.
The Angel’s plan is almost come to fruition, they have enslaved Nebelun’s golems and tamed them, and they use them to carve magical runes all over the surface of the dark side of the unspinning moon (blasting them with fire to melt the runes in and make them permanent), these magic runes have taken decades to complete, turning the moon into a weapon that will rip through the fabric of the prime material plane, leaving a permanent hole as it blasts into the pyramid that hangs over the primal volcano where on Imix makes his lair, destroying the Primordial fire lord utterly.
The angels have worked tirelessly for nearly two hundred years, driving the golems on as slave masters, enchanting, and trying to drive away the lingering power (what they call corruption) of the essence of Nebelun, what the angels refer to as the “dark trickster”.
The Company of the Shadowed Moon did what they always do, something brash. Figuring that this Keystone must be in the Ziggaraut in the Radiant City they simply decided to raid the place and steal it, killing the few angelic guards within and taking the stone with little real difficulty. Then slipping away as quickly as they could and finding their way back to the Meridian Ghost (which most of the Silvery Host seemed to be searching for, violently), the Company of the Shadowed Moon gave the Keystone the their gnomish inventor, with the hopes that he might know a way to destroy it.
The gnome did in fact destroy almost upon the instant of touching the Keystone, it turns out that the largest portion of Nebelun’s essence had reformed into an immortal and insane gnome on Faerun about 100 years ago, and this gnome despite his madness, had managed to effect a rescue mission for himself, with the Company of the Shadowed Moon as his agents. Now the avatar of Nebelun once again the gnomish inventor went on to explain what he could, even as the Meridian Ghost started off back to Faerun.
“They keystone itself has become the firing mechanism for the moon, which will rip through the layers of the planes at an increasing velocity until it buries itself into the heart of the fire Primordial’s realm , this will have the unintended consequence of leaving a wound in the sky above Toril, through which demons and elementals all every tyrannical horror that exists in the Elemental Chaos will be able to escape through onto Toril.”
Elemental monsters and demons would pour from above, effectively ending all life on Toril under its evil tide. The moon’s firing process however cannot be enacted without the Silent Keystone, only the soul of a god will provided the catalyst needed to send the magical ordinance hurtling through the planes below, the release of Nebelun had rendered the angelic weapon useless.
The wrath of angels who had come to serve the concept of revenge however, would be pointed squarely at the Company of the Shadowed Moon.
The avatar of Nebelun apologized that he would not be able to help the party, the rules of the gods where quite clear, he must return to the Astral Sea, the gods had long been barred even in their Avatar form from the Prime Material Plane, and now that he was free of the Keystone, he must return. But, with a (still slightly insane) smile Nebelun assured the party that the Meridian Ghost was perhaps his greatest invention, at least the greatest invention lying around Faerun.
“The ship always knows where you need to go, trust in that.”, the divine gnome said as he started to fade from the Prime Material Plane, “And the cannons aren’t bad either”, he included with a wink.
With all these sudden revelations weighing on their minds, the Company of the Shadowed Moon heard the beating of large feathery wings, turning and drawing their weapons, they knew the Silvery Host, the angels of revenge, would soon be upon them.
