Kirl bit her lip. Could she really trust the elf? She decided she would, because, for Kirl, at least, swearing on her own kind would mean a lot.
"Okay, I'll let you go," she said, walking over and picking up the elf's knife, so the elf wouldn't be able to get her weapon. She picked it up and stuck it in her belt, then she walked over to the elf. She looked over at Oax, and mentally told her to be ready for anything the elf might try.
She gripped her knife tightly, so that if the elf did try to kill her, she wouldn't be able to wrest the weapon from Kirl's hands, and then she reached down and cut the elf's bonds, ready to jump back, or attack, at any moment.
