This is the first rancor reference I have noticed in quite some time in my journey through
the Star Wars books. “Jabba would have fed Malik Carr and Pedric Cuf to a rancor and taken his chances with the Yuuzhan Vong fleet.” Those two have been negotiating with the Hutts, but not with Jabba. Apparently the negotiations would not have been so smooth if Jabba had been involved.
“Tenel Ka was suddenly standing alongside Leia, her hand resting lightly on the rancor-tooth-inlaid grip of her lightsaber.” Tenel Ka is a Jedi in the Hapes Consortium. Leia has gone there to plead for help in the war against the Yuuzhan Vong. If Tenel managed to get a hold of some rancor teeth, she certainly should be able to help against the Vong.
