Runes in good hands.

yellow castle doesn't want to interact with me, doesn't want to fight. It's called something like "onheir" or I'm doing something wrong.

How am I supposed to answer that (sorry for addressing you formally:D)? I'm happy to help if you ask something specific and understandable. From your words, nothing is clear. I don't deserve to struggle deciphering your sentences, but I still tried and came to the conclusion that the answer to your question is in the FAQ document attached to the map archive. And please, buy yourself a Russian language textbook, at least Gromov's, and at least for the 5th grade.
