...oh.
Poor wraiths. It's always good to destroy undead to free their souls, but these ones are enslaved twice over. He doesn't have a way to help them, and it hurts. Maybe if Strider wasn't afraid of using the Ring's power, he could help them -
"You mentioned Sauron before. As the one god Who gives out magic around here. So He sent the wraiths after the ring, and gave them some kind of magic to locate it?" Gord probably shouldn't make an enemy of a uniquely active evil god without good reason. "Putting it in my bag and running for Rivendell is probably the best plan, from your point of view."
"But I'm not convinced that I should take on the risk of joining you. It sounds like a good cause," meaning Gord is going to ask Strider to confirm everything under a truth spell, "but if I helped every stranger's good cause I would be long dead. And so help fewer people. And there might be something much worse around that I don't know about yet and would rather fight without making Sauron come after me."
"In the long term I want to get stronger, which will happen naturally as long as I'm doing something worthwhile, until I'm strong enough to go home. I'll also need diamond dust and eventually whole diamonds," at least he hopes so, "and some other expensive components, and a new magic sword, but I expect I can buy all that for spells."
"You know this world much better than I do." And you don't know about zone of truth yet. "Give me your best argument for why I should risk myself helping you and not someone else."
