She listened politely, and then beckoned for the young man to bring Wren inside. Her dark eyes scanned the both of them before Sable left. She looked at Gehrhart with a knowing glint in her eyes, and purposely left the door open, so as to let Gehrhart supervise her if he wished. She scowled at the filthy rag on Wren's arm.
"The only compensation I need is knowing you'll bring any more of your injured caravan directly to me or another healer instead of trying to use disgusting rags like this to try and bind a wound. Had you waited any longer the rag would have no doubt caused an infection, and the poor boy no doubt would've either lost this arm or died," she said without looking up, tossing the rag dismissively aside and producing a clean one, which she set at her side.
Then she set to work, her slender fingers gently prodding at and around the wound and up and down the arm. She waved the other young man aside, but let him watch. Perhaps he would learn something from watching her. Young people tended to be rather clever. Especially observant ones. She made sure to clean the wound out well, along with setting it and immobilizing it in a splint.
After her work was done, she then took a bit of the spare bandaging and made it into a small pouch with some herbs inside and handed it to Gehrhart. "These are for his pain. They can be mixed in with whatever he drinks, but only mix in a pinch. They're rather concentrated, and cause significant drowsiness. Too much will either make him sick or kill him. I've already given him some. Let him sleep once you get back. As long as the wound is kept clean and he doesn't use that arm for about a month and a half, he should be fine. Make sure he moves it around a little, though, or else the resulting stiffness of immobility will be even worse," she instructed flatly.
