From version 8.4 to today that city has had many secrets, the most relevant thing I have seen with respect to the issue is the old passage in the mines to the right of the npc malech in kazordoon and north of the npc Nokmir in beregar , I haves tried multiples dialogues with the npcs of both cities, the closest thing was the poem of the npc lokur and the question to the NPC Drog:
Borbow Delix : malech
16:34 Drog: Ohoh, I gotta go now. Just remembered that I have a rotworm in my oven.
the malech npc was added in version 9.8
