I discovered two parts of the weapon, the dwarf Dombur wants to build. But he obviously needs three parts. So I tried to search the Internet (how did we life back then without?!) for help and found the coordinates x06 y07. But this is no help because there is nothing on these coordinates.

Now I discovered this map here (Thanks for that!) where some rooms are marked, which could be the corresponding coordinates but how do I go there?

I would appreciate your kindly help.

I got it!

First I got the magic flint with the chisel for Sarding to fire the forge.

Then he repairs the throggisch key.

Then I free the Dragon-Lady with the throggisch key.

After the Dragon-Lady flew away I discovered the third part of Domburs weapon.
