-Extortusshis is one of Silverdrops five artifacts, six if you count the lost throne. But it was not made by a dwarf from here, in fact it was not made by a dwarf at all. We got all the time in the world so I might aswell tell you the legend.
It takes place in a time before time when gods still ruled the four corners of the world, long before the dark horrors were locked away. Armok's insatiable thirst for blood led him on a hunt, a neverending hunt where he would seek out every living being and slay them for his amusement. This went on for many centuries before he was banished to the depths of the earth, it was during this time that a certainly extraordinary event took place. Armok's hoardes of dark beings never met any resistance on their march throughout the lands, often their preys had already taken their own lives upon seeing the dark shadow rising over the horizon. However one day when his army charged through a small dawrven settlement something strange happned, the population of the fort was quickly extinguished but for one. Not only did the lone dwarf ignore the callings of death, he accually stood his ground and fought the neverending masses, Armok supposedly sat and watched the carnage for three days and three nights. When the sun rose on the third day Armok called back his legion of filth and malice and faced the dwarf eye to eye.
Armok question was simple-Why do you fight?
The dwarf painted red by the blood of his kin, his enemies and himself just awnsered- Why not?
From that day onward the dwarf fought side by side with the undead and demons under Armok's command, it is said that his lust for blood was surpassed only by Armok himself. Many years passed this way until something happned, something that Armok did not understand. The unnamed warrior grew old, he began losing his strength and the only thing standing in between him and death was his will to fight. Armok then disappeared for a day but upon returning he brought with him a dark gauntlet, he gave it to the dwarf whom had lost both his arm and his sight. The gauntlet was however no ordinairy gauntlet for it held the power to rip the lifeforce from ones body, the crippled dwarf fought a battle which might have been his last if it weren't for the gift he had been given. For every slash he made, for every punch he threw he could feel his old self returning...
He never regained his sight but now he could join his undying brethren in a neverending crusade of slaughter. It is said that in Armok's last fight aginst the sun and the moon the unnamed dwarf was the last to fall.
Tell them the story of Extortusshis.
Armok killed their moon god person. I imagine they're still angry about that, so we might not want to tell them about his involvement.
Edit:
Maybe they know about that the artifacts are related to Armok, and think that they might be able to get the moon's head back through them? It's insanity, but I guess metal allergies have a way of making one desperate.
Edit2:
Hmm, well, if they wish to reach Armock himself through the artifacts, that'd be easier if we were to secure them a dwarven fort that holds five others.(And I have a plan ready for that scenario.) Not to mention that being deep enough under ground will bring them closer to him, if we were to believe the old man who gave us memory smoke.
