Is there anything specific? I'm especially interested in any unique items from Middle Earth. Like how Frodo had Sting, Aragorn ad Anduril, etc..
I'm not terribly concerned with power level, either. The basis for the campaign is that Morgoth is on the verge of escaping the void. Sauron doesn't want that to happen and is, in his usually nefarious way, working to prevent it. Part of that is hunting down troves of powerful magic his minions can use. The party, of course, stumbles into the mix. The way Sauron works (infiltration and assault) doesn't lend itself to them figuring out he's actually the good(ish) guy this time around. So, of course, they go about trying to stop his plans. Part of that includes getting to the troves before his minions can.
Eventually they'll end up going against Morgoth's spawn and minions themselves, either with or without Sauron's help.
