Set Harth vs Githany

who wins who dies?

It could go either way, but I'd probably go with Githany. She was a top student at the top Sith academy. She helped Bane train and surpass Sirak. She wouldn't be able to manipulate Set like she did with Bane though.

She herself was still significantly inferior to Siraak, though. Think I'm going with Set.
