Ok, let's see if we can crack this :)
- right-click either one of the statues. You memorize the symbols.
- talk to Helga. You tell her about the statues and try to describe the symbols, but she wants you to show them to her more directly.
- use the stick (found in front of Tarik and Masha's house) on the patch of sand in front of Helga. You draw the symbols and she tells you they mean "mother's blessing" and "king's blessing".
- now talk to Masha. If you have examined the room, she should give you her blessing.
- this should also allow you to visit the king once you get a "royal" seal. Otherwise the clerk doesn't let you in, you must first state the reason of your visit, which is to ask for the king's blessing.
