The context
"It was a clear cold morning, my child, and Hareetha knew she was doomed. Behemoth Mountain lay in ruins, but I could hear her laughing. For was her god not the god of ruin?"
This context is from a text-based game made by Choice of Games. I am confused about the meaning of the last sentence. It might be an easy sentence because I know the meaning of every word. But I am not an English native speaker so I cannot understand the real meaning of it.
Thanks for elaborating.
