Testers needed.

Thank you. However, I disagree with you regarding the library: firstly, if you click on the building, it displays in yellow on a brown background what kind of building it is; secondly, the message that appears when visiting the library explains that the shack is not a library, but only a porch, and the library itself is located inside the mountain; thirdly, the wizard clearly explains the location of the library – near the place where Mirkar used to be.
Okay, I'll place the mentor on the plateau with the tower-enhancer. I'll replace the reinforcements in the dungeon with a pile of scrap metal. I'll write the descriptions of the green knights' specializations, but I can't promise biographies.
Regarding Agbeth – it's him ;). I didn't give him Chaos, only Darkness; he learned it himself.
In what way should I strengthen the Stronghold? Give them more troops or more powerful heroes?
