It's possible that the Silver Eyes could either cause Salem extreme pain or start cleansing some of that dark corruption from her. She has to have some tangible weakness, otherwise this just becomes a matter of waiting for the brother gods to intervene and save everyone. For me the SE theory is the most reasonable, though it does call into question why Salem doesn't just wipe the SE warriors from the face of the planet altogether, starting with Ruby.

The only other weakness she could conceivably have is one of sympathy, where one of the protagonists (probably Oscar) talks her down and reasons with her. Though this would be an anticlimactic and boring approach to bringing Salem down.

So, yeah, I'm going with the idea that Ruby can hurt (not kill) or purify her with her SE powers.
