Can't say if she's still alive, but all the Balam Alliance Dark Guild have been hit by Fairy Tail and while OS is now officially gone since they joined CS, Grimoire Heart still has Rustytose and Kain and we know not every Tartarus member was killed. (such as Franmalth)

True they're weaker and without their Guild Masters, but they are still around regardless.
