Morte follows the rest of the group, watching over Esk. It wouldn't do for them to have lost the orc after they saved him. But along with that, Morte was a rather decent crafter when it came to making prosthetic arms. It make take Esk a bit to learn how to use it, but it'll eventually work well enough. The tengu though wasn't doing it completely out of goodness, but to see how he could remake his arm again in the future, to make it even more powerful than it was currently.
