Alkron Wyrmsong looks at you with barely contained terror. You! You have brought the orb back to this land! You will destroy us all! The terror of Oshiruk can not be destroyed! Give up your foolish quest while you still can! He grabs for the orb as you back away slightly. His claw trails across your sword as it draws fresh blood.
Alkron Wyrmsong says 'The blade in your hand begins to glow slightly. Alkron gazes down at the blade with eyes wide. His eyes snap frantically back and forth between your face and the blade, finally coming to rest eye to eye with you. His other claw subconsciously moves to cover the wound from your blade as he continues to stare directly into your eyes. `You walk a foolish path Human. No mortal has the power to destroy the chaos that is the spirit of [Oshiruk]. The devourer has power beyond our comprehension. You are a fool if you think that blade will save you. The spirit of the crystalline wyrm has long since left this existence. You are alone in your quest for death.'
"Who is Oshiruk?"
You carry his spirit with you and know not who he is? Our worlds are ill fated indeed. But fate is not mine to control, and for my part I will [tell] you of Oshiruk. No warrior should fall before an unknown enemy. It is the legacy of my people, but I fear it will end here with all our deaths.
"Tell me."
Alkron Wyrmsong says 'Very well Hahn. Millennia ago at the height of the Dragorn empire, a dark portal opened to the north. Not far from the halls of Anguish. We soon found ourselves under siege from a dark army. While we were surprised by their initial appearance, we Dragorn are not weak and were able to fight them back to the portal itself after years of war. Ten years to the day after the opening of the portal, mere days before we would have been able to destroy the portal, Oshiruk first set foot on our world. Oshiruk was rumored to be a dark deity from a reality overcome with discord long ago and that he had come to power by consuming the other deities of his pantheon. He brought a wave of destruction across our world, killing any and all dragorn kin that were sent against his [armies].'
"His armies?"
Alkron Wyrmsong says 'Eventually the armies of Oshiruk stood at the gates of Dranik. The hordes of demonic creatures clawed at the gates as we prepared our final defenses, fully expecting to meet our final demise. But the Dragorn were not destined to fall that day. The priests of Vesagran stood stalwart at the gates of our city and that day our god answered us. A great cry was heard and great crystalline wings flapped across the city blowing up an enormous cloud of dust. The titans clashed and ultimately Oshiruk fell that day before the fury of the crystalline dragon. As he struck the ground, Oshiruk's body was consumed in [darkness].'
"What darkness?"
Alkron Wyrmsong says 'Dark tentacles lashed out around the corpse and struck the dragon, sending ripples of dark energy across her crystal scales. A cloud of discordant energy swirled in the air above Oshiruk's body. It began to come together into a globe. When the tentacles finally died away, all that was left of the mighty Oshiruk was his infamous dark armor, the gauntlets, boots, greeves, and a globe of discordant energy. The chestplate held a black orb that crackled with dark lightning. The dragon reached forward and tore the orb from the chestplate, causing a cataclysmic backlash of evil energy. She collapsed to the ground, overcome by the dark energy. The priests of Vesagran were able to protect her from the remnants of Oshiruk's army, but were not able to keep them from taking the black armor back through the portal to discord.'
Alkron Wyrmsong says 'But Vesagran held the orb, and with it the spirit of Oshiruk. The orb and Vesagran have never been seen again until today. How it might be destroyed I don't know, but should the armor ever be reunited with the orb Oshiruk would surely return and destroy us all.'
==============================================
Speculation--
Veeshan (known as Vesagran by the Kuuan) claimed Kuua long before Norrath. She favored the Dragorn so much, that she came to their aid in their time of need. Ages ago (before the Legion of Mata Muram over-ran Kuua) armies of Discord tried to conquer Kuua, and failed, because of Veeshan.
Fearing the reconstruction of Oshiruk, she then headed to Norrath, and made her mark on Velious. Her children there, the Dragons and Wyrmkind, were entrusted with this Dark Orb, and it was eventually forgotten.
One of the greatest dragons of the First Brood, Hsagra, was given the task of guarding the Orb, and her great spirit, and draconic magics had kept the Spirit of Oshiruk at bay within the Orb.
Then, as fate would have it, she was killed by King Tormax, and he gained possession of the orb. Not knowing the purpose of the orb until much later, he kept it safe.
--------------------------------------------------------------------
This is where the bard epic 1.5 picks up, with Tormax trying to control Hsagra to destroy the rest of the Dragons, to take control of the lands of Velious, and possibly further.
Then later, in the Plane of Torment, the Orb changes Metala into a monstrosity that you have to kill. Cool!
-- Finally, some lore that *almost* makes sense.
