Alright. Time to review. How did yesterday go?
He agreed to join a very dangerous quest. He did so because -
Strider said there's a Lawful Evil god Who already rules a country here, like Asmodeus in Cheliax. The wraiths work for Him and if they get the ring they'd take it to Him and He'd become much more powerful and conquer the whole continent. Gord confirmed this with a truth spell and he feels confident in that part at least, Strider doesn't seem experienced enough with magic to throw it off undetectably.
So he came back to the ring and gave up his bag of holding to hold it, maybe indefinitely. (Something he'd declared just before he wouldn't do). Also, the ring is known to enchant people into wanting it and staying around it, and he wanted to leave it behind for this reason but was convinced to come back anyway. At one point he was worried that Strider might be enchanted (or cursed or however that works), and then - promptly forgot about it? And everyone felt and acted weird when it came time to put the ring in the bag - well, maybe Strider didn't - Gord still can't be sure if he just imagined it or if his will really was being swayed a little.
These aren't details he knew or anticipated when he agreed to join this party, but they're within the bounds of what he expected; the ring is dangerous. But that doesn't mean his decision to come back was wrong. He learned something new and important and acted on it.
Should he have done something more to guard against enchantment? Can he do so now? He would prepare Enchantment Foil, except he has no free fourth-circle slots for the foreseeable future. Not succumbing to the curse is more urgent than not being slowly enchanted.
And he is in fact still cursed (if that's what it is). Strider thinks his friends in Rivendell can remove the curse so it's good Gord joined up with him, but he didn't know that at the time. This is a decision from his first day in this world coming back to bite him, and he already realized fighting the wraiths had been a mistake.
He should have thought of Enchantment Foil yesterday, and Protection from Evil and other spells that might help with enchantments. Lack of sleep is no excuse; he didn't spend the walk back trying hard to think of something. He needs to do better.
Overall, it was a day certain to go down in (Gord's personal) history, but it may be some time before he learns the consequences. (Unless the wraiths find and kill them all next night.) He doesn't think he was wrong. It was a very high stakes decision, but it still seems like the right one.
