Abduxuel and Levena together went investigate after hours, as the first son nor his slave had not been found. They figured that there was no living duergar camp whatsoever. Duergars had been driven off ages ago. Now, what's all left were three factions; a demonic army led by a cambion general, illithids who wanted to claim the cavern and were in shadows manipulating things and lastly a dracolich who used army of undead duergars to wage war against the demons.<br/><br/>But their mission was not to fight neither side, just to find the gemstone. As it happens, they found a duergar ghost which Abduxuel bound under her command (temporally) who had been a royal guard of the last duergar king. Captain even. However, he told the king fearing the ancient treasure stolen, disappeared on the day of the attack when dracolich invaded the city with an army of the undead and demon allies (the reason they waged war was that they had a disagreement about spoils and size of it). However royal guard speculated king had hidden his main treasure and is waiting to reclaim it.<br/><br/>So with that hint, they studied the dwarven king palace which had been crumbled down and destroyed in the conflict between armies of undead and demons, they did find a secret mechanism that conjured a stairway in the vault which had been breached. They soon found the chamber with lots of royal guard members, slain by fiery magic. But suddenly become animated as the last duergar king of the city was pretty much become a ghost, a greedy spectre, who jealously guarded his remaining hoard against anybody! A battle ensued, but Abduxuel and Levena were victorious (the archangel was a great deal of help as well thanks celestial abilities). The remains of last duergar king's treasure were theirs now (ghost no doubt manifests once more but is bound to location so cannot pursue). They did find gemstone and some 'choice treasures' the duergar king had stored there.<br/><br/>But there was not much time to study or identify treasures, as dracolich and demon general both had figured out what they were doing (somehow, suspicion on illithids), so army on approaching their location and still haven't found the first son and his slave the duo used the disks to shatter them and teleport back to the house with their goods before any magic or countermeasure by any parties against teleportation is placed in. After glimmer, they appear just above the house symbol in the main entrance chamber. Some slaves and house members became alarmed but calmed down once seeing who they were and then gave proper respects and continued on their daily lives. Even guards smarter than even 'doubt' who they are, albeit chance for illusion disguise is possible but greater wrath or punishment in holding Abduxuel still for inspection than later admit being fooled by the bold illusion.
