Fortunately, the corbies don't use the greatest combat tactics, mostly consisting of 'charge blindly'. It's also a narrow hallway, which means that she can hold them at bay, fairly easily; only two can get close to her, the third in the back, squawking in frustration. She lands a clean hit, and easily deflects their attacks, and Flare shoots her crossbow over Rimeera's shoulder, and hits, dropping the already injured one... and letting its complaining companion step into its place.
