Goblins/Elves: We pledge to help you in your quest.
Goblins: Our numerous and diverse army will follow you into whatever battle fate may bring. We will change our culture, and even change our very bodies, to better serve the cause.
Elves: We can, uh, sell you this bow. And teach you how to make arrows! (On your own. From your own materials.) And teach you ecomancy! (It’s not very useful on its own.) Oh goodness gracious, look at the time! You need to go slay the Demon Lord! Good luck~!
